1640: Nicola Sanders poses for the photographers with her gold medal after her outstanding display in the 400m final.

1637: The final action of day two is the high jump section of the men's heptathlon.

The Czech Republic's Roman Sebrle jumps 1.93m with his one and only attempt, and he extends his lead at the top of the overall standings after three events.

1629: Portugal's Naide Gomes makes the longest jump in the world this year to win gold in the long jump.

Her effort of 6.89m pushes Spain's Concepcion Montaner into silver and the Czech Republic's Denisa Scerbova into bronze.

1622: Ireland's David Gillick produces a performance full of character to defend his 400m title in thrilling fashion. He overtakes Germany's Bastian Swillims in the last few strides to win in 45.52, a new Irish record.

And Britain's Robert Tobin also digs deep to claim a brave bronze medal. He edges out Sweden's Johan Wissman, who seemed to run across Tobin's line, by two-hundredths of a second.

1613: Brilliant display from Britain's Nicola Sanders as she takes the 400m gold medal in some style.

Starting from the outside lane, Sanders gets away well and her rivals never get within 10m of her.

Her 200m split time of 23.31 seconds raises a few eyebrows, but she keeps her form superbly to scorch to victory in a time of 50.02 seconds. It's a new PB and British record, and the fastest time in the world this year.

"The pressure does get to you," she told BBC Sport.

"I knew that if I didn't win, questions would be asked, so I'm absolutely thrilled."

Bulgaria's Iona Usovich takes silver, almost a second behind Sanders, and Russia's Oleysa Zykina claims bronze.

1604: "God Save The Queen" is heard at the National Indoor Arena for the first time since the opening ceremony as the medal ceremony for the men's triple jump takes place.

1600: More disappointment for Great Britain as Helen Clitheroe finishes in fourth place in the women's 1500m final.

Clitheroe also finished fourth at the 2005 Championships.

She tries to kick clear with two laps to go, but finds herself run down by eventual winner Lidia Chojecka and silver and bronze medallists Natalya Pantelyeva and Olesya Chumakova.

"I'm absolutely gutted," she told BBC Sport.

"I really thought I could get a medal today, but it seems the curse of fourth place is on me again which is very depressing."

1545: Disappointment for Britain's Mo Farah as he finishes fifth in the 3,000m final. He tries to force the pace in a slow race, but is clearly not at 100% as he has to step back off the throttle.

His fall in Friday's heat clearly affected him, and he is unable to get back on level terms with the leaders.

Italy's Cosimo Caliandro claims a surprise win, with France's Bouabdellah Tahri in second and Spain's Jesus Espana in third.

1539: Germany's Danny Ecker claims gold in the men's pole vault ahead of Ukraine's Denys Yurchenko and Bjorn Otto of Germany. They all clear 5.71m, with Ecker taking the title on countback.

1537: "Mo Farah comes out smiling before his 3,000m. He is warming up around the track now and there's no sign of that calf injury."
BBC Sport's Sarah Holt in Birmingham

1533: Craig Pickering makes it three out of three for Great Britain as he books his place in the men's 60m final alongside team-mates and training partners Jason Gardener and Ryan Scott.

Pickering finishes in 6.58 seconds, exactly the same time as Gardener.

"That was much, much better - that was my best performance for a while," Pickering told BBC Sport.

1529: "Phillips Idowu was in high spirits down in the mixed zone after winning a gold for Great Britain.

"In an Oscar speech moment the 28-year-old thanked his physio, coach, doctors, friends, family... probably even the bloke at this piercing parlour given the new ruby red stud in his ear.

"Birmingham-based Nathan Douglas was pleased with his silver but said about his and Phillips' chances at August's World Championships: 'We could win gold and silver again or come seventh and eighth - that's how strong the triple jump is'."
BBC Sport's Sarah Holt in Birmingham

1520: Jason Gardener is on top form in the men's 60m semi-finals. He wins his race ahead of France's Ronald Pognon in 6.58 seconds, while Britain's Ryan Scott finishes third with a PB of 6.63 seconds.

"I feel back to my old self," Gardener told BBC Sport.

"I was in control from about 20m out and I didn't make any mistakes."

Ireland's Paul Hession also makes the final as he come through in fourth place.

1511: Belgium's Kim Gelvaert has too much class for the rivals in the next women's 60m semi. She sets a new PB, national record and the fastest time in the world this year with a time of 7.10 seconds.

Katerina Thanou is second with a time of 7.22, but Britain's Montell Douglas is just pipped for a place in the final as she comes fifth - just one-hundredth of a second off fourth-placed Magdalena Khristova, while Joice Maduaka comes seventh.

1505: Earlier, in the men's 800m semi-finals, there was no luck for Britain's two representatives Richard Hill and James Brewer. With only the first three in each semi going through, they finished fifth and fourth respectively.

1500: Britain's Jeanette Kwakye makes the final in the 60m with an outstanding performance in her semi-final. She secures a huge PB with a time of 7.17 seconds to finish well clear of the field.

1442: In the 1500m heats, Britain's Chris Warburton looks to be out of the running after falling in his race.

But his team-mate James Thie takes advantage of a fast race in the second heat, clocking a time of three minutes 44.15 seconds, and could go through.

Spain's Juan Carlos Higuero has set the standard so far with a time of 3:43.02.

1440: That's it - gold and silver for Great Britain in the triple jump. Phillips Idowu fully deserves his title after a massive jump with his first attempt. He adds this to his Commonwealth title.

It was a high-quality competition between two high-quality athletes. Nathan Douglas can be proud of his performance.

The pair parade around the arena draped in union jacks to the delight of the fans.

1431: Nathan Douglas is in red-hot form but he cannot quite get close enough to Phillips Idowu. He jumps 17.41m with his fifth attempt, his fourth distance over 17m.

1425: "Who says the Belgians are boring? Great high jumping. Is Tia Hellebaut fuelled by Belgian buns?"

1420: Belgium's Tia Hellebaut wins the first gold medal of the day with a dominant performance in the women's high jump. She clears 2.05m, setting a national and Championship record in the process.

Italy's beautifully-named Antonietta di Martino takes silver, with Venelina Veneva in bronze.

1405: It's all going well for Britain's 800m runners in the women's semi-finals.

Marilyn Okoro sets a PB of one minute 59.87 seconds to qualify in third, and Jenny Meadows follows it up with a time of 2:00.79.

Meadows dedicates her performance to close friend Karen Harewood who suffered a broken leg on Friday (see 1342 entry).

1400: Nathan Douglas is not going to let Phillips Idowu have things all his own way. He jumps a personal best of 17.47 with his third attempt, just short of his team-mate's mark.

1355: "I've just spoken to a UK Athletics spokesperson here and Mo Farah is warming up as usual ahead of his 3,000m tilt at 1540.

"According to his coach, Alan Storey, he will race so long as nothing goes wrong in the warm-up. Keep those fingers crossed."
BBC Sport's Sarah Holt in Birmingham on Farah's calf injury scare (see 1315 entry)

1350: Hats off to Britain's Phillips Idowu. He absolutely nails his first attempt in the triple jump final, recording a massive 17.56m - the longest jump in the world this year.

It's a Championship record and just eight centimetres off Jonathan Edwards's British indoor record and the rest of the field will be hard-pressed to match it.

It was a superb response from Idowu after his British rival and team-mate Nathan Douglas had jumped 17.08m just before.

A potential gold and silver here for Great Britain.

1342: The latest update on British 800m runner Karen Harewood is that she did indeed suffer a broken leg when she got caught up in a tangle of legs in her heat on Friday.

She underwent surgery in Birmingham on her left leg on Saturday.

And Harewood has also received messages of support from the Russian Federation. It was their athlete Mariya Shapayeva who accidentally clipped Harwood to cause the pile-up.

1340: The women's high jump final is under way, but there is plenty of life left in the competition yet. Seven of the eight athletes are level at the moment having cleared 1.92m.

1330: "British medal hopes Phillips Idowu and Nathan Douglas are warming up ahead of the men's triple jump final.

"Douglas is ranked number two in Europe with a mark of 17.19m while Idowu, with a bleached blond, well almost yellow, barnet is seventh in the rankings."
BBC Sport's Sarah Holt in Birmingham

1326: After two events - the long jump and the 60m - the Czech Republic's Roman Sebrle holds a narrow lead in the heptathlon.

Sebrle has 1868 points, with Russia's Aleksandr Pogorelov 19 points behind and Andrei Krauchanka another four points back in third.

1321: "Things are getting sticky in the BBC commentary box - quite literally.

"The hotel where the Beeb crew are staying ran out of water in the early hours of this morning, meaning there was zero chance of anyone having a shower this morning - or even washing their hands.

"Pity the guests who only discovered that they couldn't flush their toilets when they'd stood up again..."
BBC Sport's Tom Fordyce in Birmingham

1315: Bad news for Mo Farah and British fans. According to BBC commentator Brendan Foster, who has spoken to the athlete's coach, the European silver medallist is "touch and go" for his 3,000m final at 1540 because of a sore calf muscle.

Farah fell in his heat on Friday, and had to work very hard to get himself back into contention, qualifying as a fastest loser.

But Farah went for a light jog this morning and has since complained of pain in his calf.

1300: "Olympic high jump champion Stefan Holm was pretty relaxed after qualifying for Sunday's final with a leap of 2.30m.

"The Swede spent ages in the mixed zone chatting to his national press and then said he planned to unwind by watching Liverpool, who he has supported since he was a youngster, against Manchester United in his hotel.

"Britain's Martyn Bernard was also full of smiles after qualifying with a new personal best of 2.30m. He says he was just relieved to literally get the height over and done with.

"He reckons the final here in Birmingham is every bit as tough as an Olympic final with super Swedes Holm and Linus Thornblad and in-form Russians Andrey Tereshin and Ivan Ukhov in the field."
BBC Sport's Sarah Holt in Birmingham

1255: The tension is building ahead of the afternoon session, which includes the finals of the men's triple jump (1335) and 3,000m (1540) as well as the semi-finals of the men's 60m (1520) featuring British hopes Jason Gardener and Craig Pickering. The day concludes with the men's and women's 400m finals (1610).

1245: Qualifying for the women's shot put has ended.

1155: There is no British interest in the women's shot put, but three athletes have already made sure of their place in the final.

Russia's Olga Ryabinkina, Italy's Assunta Legnante and Yulia Leantsiuk of Bulgaria have all gone beyond the required 18.00m mark.

1124: Something of a lull inside the arena at the moment, but fear not - qualification for the women's shot put starts at 1130.

1100: "There were actually ticket touts outside the NIA early this morning - that's how excited Birmingham is about day two of the European Indoors.

"Both Saturday and Sunday are sell-outs here, although the arena is no more than a third full at the moment. Must be something going down at the Bullring or Cadbury World."
BBC Sport's Tom Fordyce in Birmingham

1051: Britain's Chris Tomlinson starts off his long jump qualification bid with a decent 7.96m leap, his best of the season.

The 25-year-old seems to look less like the archetypal student than he used to. In fact he reminds me of the gravely-voiced singer Tom Gray in indie band Gomez.

1048: Martyn Bernard is really enjoying himself in the high jump. He sets another PB - his second of the day - by clearing 2.30m, guaranteeing himself a place in the final.

1045: "Roman Sebrle, the defending heptathlon champion, is just glad to be on the starting blocks for the 60m after being hit by a javelin in training earlier this year.

"He says: 'If the javelin had hit me 10cm to the left, it would have punctured my lung - 20cm higher, my throat...'"
BBC Sport's Tom Fordyce in Birmingham

1030: Britain's Martyn Bernard is going well in high jump qualification, currently in second place with a PB clearance at 2.27m.

1025: Britain's Jason Gardener is in no mood to give up his title without a fight. The 31-year-old blasts out of the blocks and destroys the field to win in a time of 6.59 seconds - he virtually jogs the last 10m with none of the other athletes anywhere near him.

Somewhat bizarrely, lining up next to Gardener in the blocks is Gibraltar student Dominic Carroll whose main athletics experience has come in the 800m and cross country.

Still, he records a PB time of 7.41 seconds which is quicker than I could run.

1022: Ryan Scott will join his team-mate Pickering in the semi-finals of the 60m heat with an impressive second place behind France's Ronald Pognon in their heat.

1015: Britain's Craig Pickering shows real composure to come through and win his 60m heat. After two false starts, with Gibraltar's Daryl Vassallo disqualified, Pickering makes a slow start and trails Ireland's Paul Hessian at the halfway stage.

But the gold medal favourite keeps his form and comes back into the picture to edge Hessian out in a photo finish, with both given a time of 6.61 seconds.

1010: One for the "What Happened Next?" round on Question of Sport. Spain's Naroa Agirre gets several feet in the air trying to clear a height of 4.50m only to see her pole snap in two.

She crashes to the ground and is lucky to just land on the mat and avoid any serious injury.

1005: Good news for Britain's women sprinters - all three go through to the semi-finals as fastest losers.

1004: On her return to top-level competition, controversial Greek sprinter Katerina Thanou is booed by the Birmingham crowd. Thanou served a two-year ban after missing three drugs tests in the run-up to the 2004 Olympics.

Thanou seems to have a thick skin though, as she wins the heat in 7.26 seconds. Also running in the heat - at the age of 47 - is former Jamaica sprinter Merlene Ottey. Remarkable.

1003: "Italy's Andrew Howe, who has just qualified for the long jump final, has a tattoo on his arm which reads 'BMF'.

"Apparently it stands for 'Be More Faster' - a damning indictment of Howe's basic grammar, not to mention that of his tattooist."
BBC Sport's Tom Fordyce in Birmingham

0955: Britain's third runner in the women's 60m heats Montell Douglas also comes third after a decent run in her heat. She gets a time of 7.29 seconds.

0953: A mixed bag for Britain's Kate Dennison in the pole vault. She sets a new PB with a clearance at 4.40m and then sets her sights on a new British record of 4.50m.

After a lengthy preparation and the usual claps from the crowd, she races down the track but drops her pole and runs straight onto the landing mat. You can only assume she lost her bearings on the way. Still, she has two more attempts at the height.

0947: Belgium's Kim Gevaert shows she's the woman to beat in the 60m with a classy victory in her heat. A time of 7.17 seconds should send out a message to her rivals.

0943: So far in the men's long jump, France's Salim Sdiri is the only athlete guaranteed a place in the final. He jumps 8.00m on the nose with his first attempt - the exact distance required for automatic qualification. Job done.

Incidentally, Sdiri has five snakes and four tarantulas back at home. Just in case you were wondering.

0940: Another third place in the women's 60m heats, this time for youngster Jeanette Kwakye who clocks a time of 7.27 seconds.

0937: Britain's Joyce Maduaka squeezes into third place in her 60m heat in a time of 7.30 seconds. It's very tight, and she'll have to wait to see if she is one of the six fastest losers to go through to the semi-finals.

0923: The action is under way at 0930 on day two at the National Indoor Arena in Birmingham, with qualification for the women's pole vault and the men's long jump and high jump the first events to get going.

Later on, Craig Pickering will look to justify the buzz surrounding him going into the Championships when the heats for the men's 60m start at 1000.
