Newquay Cormorants' Jonathan Fox set a new world record in the S7 100m backstroke on Thursday as he booked his place at the Beijing Paralympics.

The 16-year-old swam in one minute 14.86 seconds in his heat at the British Championships, adding to his record in the S7 50m backstroke.

He went on to win the final, taking the British title and a Paralympic place.

His coach Phil Goldman puts the record down to the Great Britain training camp Fox attended in Australia in January.

"It's a big step, but he's matured quite a lot over the winter," Goldman told BBC Radio Cornwall.

Goldman added that Fox has only recently been able to get strong enough to swim 100m backstroke since being at the Gold Coast camp.

Fox's achievement caps a good few days for Cormorants swimmers.

Matt Whorwood also qualified for Beijing in the S6 400m freestyle event.

Whorwood is the second fastest in the world this year and is another good prospect for a British medal.
