Sprinter Dwain Chambers has been included in Team GB's athletics squad for the Olympic Games in London.
The 34-year-old, who won the 100m Games trials, can compete after the British Olympic Association policy of
lifetime bans for drug cheats was overturned.
Jessica Ennis, Mo Farah, Phillips Idowu, Dai Greene and Christine Ohuruogu are among GB gold medal hopes.
Only one woman,
Lynsey Sharp, is picked for the 800m
with 2009 world bronze medallist Jenny Meadows missing out.
Meadows, who had indicated before the team announcement she would appeal if not selected, has decided not to fight the decision.
Team GB's recent Olympic athletics medals
Total - 4. Gold 1 (Christine Ohuruogu 400m) Silver 2 Bronze 1
Total 4. Gold 3 (Kelly Holmes 800m and 1500m, 4x100m relay) Bronze 1
Total 6. Gold 2 (Denise Lewis heptathlon, Jonathan Edwards triple jump) Silver 2 Bronze 2
The 2010 European bronze medallist suffered a setback when
she pulled out of this year's Euros
before her 800m race in Helsinki on Saturday after aggravating an Achilles injury.
Marilyn Okoro, Emma Jackson and Jemma Simpson were other 800m contenders hoping to run in the women's event.
A total of 71 athletes were added on Tuesday to the six previously-named marathon runners to complete the GB athletics squad, which has been set a target of eight medals, including at least one gold.
Defending 400m title holder Ohuruogu, Ennis (heptathlon and 100m hurdles), Farah (5,000m and 10,000m), Idowu (triple jump) and Greene (400m hurdles) lead the gold medal prospects.
Adam Gemilli, 18, is the youngest member of the squad and one of three athletes picked for the men's 100m alongside James Dasaolu, 24, and Chambers.
Chambers was banned for two years
after testing positive for the designer drug THG in 2003.
Chambers records 100 metre trials win
He won the 100m trials in Birmingham in 10.25 seconds - seven hundredths of a second outside the 'A' qualification time required - and
did not run in the 100m at the European Championships
. However, he ran 'A' times last summer, which the selectors could take into account.
"For me representing my country in an Olympics is a privilege that should never be taken for granted," said Chambers.
"To be given the opportunity to do so in my home town has been a dream that at times has seemed very distant and is now a reality."
One of the toughest choices facing UK Athletics was which of five contenders to pick for the women's 800m.
Three runners could have been chosen and head coach Charles van Commenee said a third of the six-hour selection meeting was taken up by discussing the event before plumping for Sharp, the only one of the five without an A standard time.
"We decided she was the one with best current form. It was difficult because not one of the athletes took control of their own destiny," he said.
"Team selections are always going to have people missing and the women's 800m is the most contentious. Charles van Commenee is basically saying the four girls that got the A standard aren't going to be able to produce at the Games, whereas there are probably other people in other events that you could say the same thing about. It's a lack of consistency."
"The athletes made it difficult by not doing what they're supposed to do. Once the selection panel has to spend two hours it's already a bad sign.
"The panel and I are convinced that the athlete selected is the one who has the best chance of performing well at the Games."
Okoro and Jackson have run the 'A' standard this year but finished fifth and seventh respectively at the Olympic trials - won by Sharp, who also
claimed a European silver medal.
Meadows, who has not raced this year because of injury, and Simpson achieved the A standard in 2011. Simpson was second in the trials but finished seventh in Helsinki.
A Team GB statement read: "International rules of sport mean an athlete who has achieved the 'B' standard can only be selected if there are no 'A' standard athletes in that event selected to the team."
Shortly before the team announcement, Okoro, who is in the 4x400m team, said
"I'm quitting". She later deleted the tweet.
Van Commenee said: "Hearing the news that you are not part, that you can't compete in your favourite event in the Olympics is not easy to digest and it's not easy to give that news.
Appealing selection decision
- Athletes have 24 hours to lodge a written appeal
- Appeals can only be made on the grounds selectors had facts wrong or did not properly employ their own criteria
- Outcome of any appeals expected on Friday afternoon
"When I spoke to her on the phone, she indicated that she would quit. I want to see how that goes in the next few days."
The Dutchman, who has admitted he is braced for a "heap of appeals" from athletes, said it was not easy to leave out Meadows.
"It was very difficult because she has a proven track record. She's absolutely a world-class athlete. However, she has not raced since the  World Championships in Daegu," he said.
Sprinter Richard Kilty said his own exclusion was "an absolute disgrace" after posting two A standard times in the 200m and he planned to appeal.
"I am 100% fit, with two A standards, three spots available and they say no, and there's five slower athletes than me in the relay - they have a personal problem with me."
Three athletes are the head coach's own discretionary picks - Nigel Levine (men's 400m), Lee McConnell (women's 400m) and Julia Bleasdale (women's 5,000m).
European high jump champion Robbie Grabarz will make his Olympic debut, while Greg Rutherford has a genuine medal chance in the long jump.
Eilish McColgan, 21, the daughter of former 10,000m world champion Liz, will represent Britain in the women's 3,000m steeplechase.
World bronze medallist Andy Turner has been selected for the 110m hurdles.
Chambers was joined in the squad by another athlete previously barred due to a drugs ban, with Carl Myerscough selected in the shot put.
Myerscough achieved a second B standard in the shot just hours before the deadline by seeking out a minor meeting in Estonia and
catching a ferry from Helsinki to Tallinn
late on Saturday night.
