Both sprinters have been waiting anxiously since last Saturday's race when Chambers won in the fastest time by a European athlete this year of 10.00sec with Williamson in his slipstream.

 

Williamson, the European Under-23 champion, was the only athlete announced in the first-wave of selections last Monday, the selectors deferring naming the other two until Chambers' High Court appearance.

 

The 30-year-old former drugs cheat lost his injunction, opening the door as expected for Pickering and Edgar to be chosen.

 

"This has been one of the strangest weeks of my life and I don't ever want another one like it," said Edgar, a 26-year-old from Newham who won last month's European Cup 100m in Annecy.

 

"I would have preferred a smoother ride, but it has been like a roller-coaster.

 

"But athletics is like that, you get the ups and downs.

 

"I was really disappointed at the trials, but I remained hopeful throughout the week I would get selected for the individual 100m.

 

"Now I have a big smile on my face, the Olympics is the biggest sporting event in the world and I'm really excited to be part of it."

 

Edgar, like many other of his team-mates, has been annoyed that Chambers' bid to run in Beijing has detracted from the performances of the 68-strong squad of whom 21 will be debutants.

 

He said: "I'm just thankful the court case is over and grateful for the opportunity.

 

"I've been getting a bit irritated with all the questions about it, but now I just want to forget about it and look forward to Beijing.

 

"I just want to take it round by round now and do the best I can."

 

Other additions include the world junior 1500m gold medallist Stephanie Twell, who has earned her place on merit rather than by inclusion under the criteria of being a potential medallist or podium finisher at the London 2012 Games.

 

The 18-year-old from Aldershot, who held the qualifier from last year, clinched her slot when running a lifetime best of 4min 05.83sec in last night's Paris AF Golden League meeting.

 

Andrew Lemoncello, who achieved a 3000m steeplechase personal best at the Stade de France, has also been selected with fellow Scotsman Allan Scott chosen for the 110m hurdles.

 

Martyn Bernard is added to the high jump squad while Rikki Fifton - always on the borderline for a 200m place - has been added to the 4x100m relay squad with Channel Islander Dale Garland joining the 4x400m quartet.

 

Montell Douglas, who smashed Kathy Cook's 27-year-old UK 100m record with a time of 11.05 at Loughborough on Thursday, has been picked for that distance along with Laura Turner.

 

Seventeen-year-old world junior 100m silver medallist Ashlee Nelson is in the 4x100m relay squad and will join her elder brother Alex, already selected for the 200m.

 

It is only the third occasion in the 112 year history of the Olympics that a brother and sister have represented Britain at the same Games.

 

The other occasions were Godfrey and Audrey Brown at the 1936 Olympics in Berlin and the 1976 Games in Montreal when Ian and Mary Stewart were chosen.

 

Jenny Meadows, who ran a personal best in Paris and Jemma Simpson are late 800m choices while after Twell's superb showing, Susan Scott has been given the third 1500m position in preference to Hannah England.

 

Former UK 3000m steeplechase record holder Hatti Dean gains her vest despite missing the trials through injury, with Sarah Claxton the sole 100m hurdles representative.

 

Zoe Derham is picked for the hammer and Vicki Barr, along with with the highly experienced Donna Fraser earning a fourth Olympic place, are included in the 4x400m relay team.

 

"We have selected a team based on tough criteria and so it should be," said UK performance director Dave Collins.

 

"It is good to see that so many athletes have stepped up to the challenge and I will be looking for them to continue their progression towards the huge challenges that lie ahead in Beijing.

 

"The process of selection is never an easy one, but we were very careful to be consistent across the board.

 

"In some events, where competition for places was particularly close we based our decisions on a three-part check of performances at the trials, season's bests and head-to-heads.

 

"We now look forward to Beijing, where each athlete has their own individual targets to meet and perhaps, exceed. Some will be gunning for medals, others will be looking to grasp this huge opportunity to learn from and develop into a podium level athlete in the near future.

 

"I can assure them that the support team behind them will give them every backing to ensure they meet their goals at Beijing 2008."
