Sotherton recovered well from a disappointing high jump

Dwain Chambers and Mark Lewis-Francis both went through to the semi-finals of the 100m but Tyrone Edgar missed out.

Rising star Becky Lyne won her 800m heat to go through, along with fellow Briton Jemma Simpson.

Greg Rutherford advanced to the final of the long jump after an impressive 8.07m in the first round of qualifying.

World and Olympic champion Carolina Kluft took control of the heptathlon at the end of day one following the withdrawal of Frenchwoman Eunice Barber through injury.

Kluft has 3,990 points after four events with British duo Kelly Sotherton and Jessica Ennis lying second and third on 3,866 and 3,861 points respectively.

Barber led after good performances in the 100m hurdles and high jump but was then forced out with a thigh injury.

Kluft has struggled with an injury and was seen in floods of tears on the warm-up track shortly before the hurdles race but somehow she regained her composure.

Although she was fifth in the hurdles, she moved back into contention with top spot in the high jump (1.89m) and second in the shot putt (14.56m)

Sotherton recovered from a poor high jump (1.77m) to set a new personal best of 14.27 in the shot.

Ennis had a personal best of 12.72m in the shot putt - one of her weaker events - and then edged out Sotherton and Kluft in the 200m to finish the day on a high.

Dwain Chambers and Mark Lewis-Francis both reached the semi-finals but both have much to do to have a chance of a medal.

Chambers, who was the fastest qualifier from the first round in 10.24 seconds, struggled in the second round and only managed 10.39 to finish fourth behind Poland's Dariusz Kuc.

Lewis-Francis followed up his 10.37 first round time with 10.33 in the second round behind France's Ronald Pognon, one of the favourites for a medal.

"I can tell you about 25 things did wrong in the race," he told BBC Sport afterwards. "But I now have to regroup and get ready for the semi-finals on Tuesday."

But Tyrone Edgar, who clocked 10.51 behind Russia's Andrey Yepishin, was fifth and failed to advance.

Tim Benjamin qualified safely for the semi-finals after winning his heat in 46.10 seconds, just ahead of Ireland's David Gillick and will be joined by Graham Hedman and Robert Tobin.

Benjamin, who has struggled with injury for much of the season, looked relatively comfortable and the win will ensure a more favourable lane draw in the next round.

"I felt quite relaxed but this was all about qualifying," he told BBC Sport afterwards. "The object is to get a good lane draw when it matters."

Hedman finished third behind France's Marc Raquil in heat four in 46.02 while Tobin went through as a fastest loser in 46.10.

Poland's Daniel Dabrowski was the fastest qualifier in 45.68.

Rising star Becky Lyne won the second of four heats with an impressive display.

The 24-year-old Hallamshire Harrier clocked 2:01.87 to edge out strong Ukranian Tetyana Petlyuk.

Lyne became the United Kingdom's third-fastest female 800m runner of all time earlier this year.

Brendan Foster, commentating for BBC Sport, said: "She's a strong and powerful athlete and did it wisely. I'm starting to get excited about her performance."

Jemma Simpson finished third in her heat in 2:01.55 behind Russian Olga Kotlyarova and Slovenia's Jolanda Ceplak.

But there was no luck for Amanda Pritchard who was tripped with around 150m to go while in a good position in the final heat.

"I can't believe it. I'm absolutely gutted," she told BBC Sport. "I was running well and feeling good."

Andy Baddeley will be Britain's only representative in Wednesday's 1500m final after both Stephen Davies and Michael East missed out.

Baddeley finished seventh in his semi-final in three minutes 41.92 seconds to go through as a fastest loser while France's reigning champion Mehdi Baala won in 3:39.74 to be the leading qualifer for the final.

"It was a quick last 600m and maybe I wasn't in the right place at the right time," Baddeley told BBC Sport. "But I did enough and I will be more aggressive in the final."

Davies missed out after finishing 11th in the other semi-final in 3:48.64 while Michael East fell while at the back of the field.

British trio Greg Rutherford, Chris Tomlinson and Nathan Morgan all reached Tuesday's final.

Rutherford looked particularly impressive with 8.07m in the first round to surpass the automatic qualifying standard of 7.95.

Tomlinson hit the qualifying mark in the second round while Morgan's best of 7.94 was enough to see him through in eighth place.

Italian Andrew Howe led the qualifiers for the final with 8.33.

Russia's Inga Abitova sprinted away from her rivals late on to win the first gold medal on the track in a new personal best.

Abitova proved strongest in a quick final lap to stay ahead of Norway's fast-finishing Susanne Wigene and her Russian team-mate Lidiya Grigoryeva and win in 30 minutes 31.42 seconds.

Ethiopian-born Elvan Abeylegesse pulled up with 3,000m left and although Lornah Kiplagat of the Netherlands took over the lead, she faded badly late on.

Kathy Butler was the leading British finisher in 12th place in a season's best 32:01.04 with Mara Yamauchi 13th in 32:07.90 and Hayley Yelling 15th in 32:12.50.

British trio Germaine Mason, Martyn Bernard and Adam Scarr all failed to reach Wednesday's final after some disappointing performances.

Mason, in his first major competition since winning bronze when representing Jamaica at the 2004 World Indoors, had three failures at 2.23m

Commonwealth silver medallist Bernard managed 2.23 but was unable to clear 2.26, which would have given him a place in the final, while Scarr failed to make his opening height of 2.15.

Norway's Andreas Thorkildsen threw a useful 86.55m to qualify in first place for Wednesday's javelin final.

Thorkildsen, who has thrown over 91m this season, looked good to beat off Latvian duo Ainars Kovals and Vadims Vasilevskis with Kovals throwing a personal best of 85.95.

Britain's Nick Nieland qualified in 11th place with a best throw of 80.40, 20cm behind the great Jan Zelezny of the Czech Republic, who will retire at the end of the season.

Germany's Ralf Bartels claimed the first gold medal of the competition with a season's best of 21.13m in the final round.

Bartels, who had the best throw in the qualifying round, was out of the medals until his late dramatic effort.

Former world champion Andrei Mikhnevich of Belarus, who had led from the second round with 21.11, had to settle for silver ahead of Denmark's Joachim Olsen (21.09).

Britain's Carl Myerscough failed to progress to the final after only managing 19.52m in qualifying to miss out by 16cm.

Russian Tatyana Lysenko threw a new championship record of 73.23m to set the pace in qualifying for the final.

Lysenko finished ahead of Germany's Betty Heidler, who threw 71.40 while the final qualifying place went to Greece's Alexandra Papayeoryiou (66.81)

Britain's Shirley Webb failed to qualify after throwing 60.30m for 34th place overall with Zoe Dirham only managing 56.94.

Britain's Lee McConnell finished fourth in her heat 56.02 but qualified through a fastest loser slot.

"I'm not very happy," McConnell told BBC Sport. "I went out hard enough but eased off in the home straight.

"I'm an experienced athlete - there's no excuse for that. Going out in the first round is not what I came here for but I've got no-one else to blame but me."

BBC pundit Colin Jackson said: "Technically she's improved a lot, but the actual running of the race was a major problem."

Fellow Briton Natasha Danvers-Smith qualified in second in her heat in 55.64, but team-mate Emma Duck missed out.

Russia's Yevgeniya Isakova was fastest in 55.21.
