The British Olympic Association today released the names of the athletes who will be leading Team GB in the track and field in August, with Dwain Chambers and Carl Myerscough controversially included in the men's team.
Chambers and Myerscough were both found guilty of taking banned substances, and while they were initially handed lifetime bans by the BOA, they had them overturned and are now eligible to compete once more.
Chambers spoke of the honour of being able to take part in an Olympics in his home country, and thanked those who stood by him through more difficult times.
"It is a real honour to be selected as part of Team GB today," he said.
"For me representing my country in an Olympics is a privilege that should never be taken for granted. 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.
"It is now my responsibility to prepare fully for the 100m, the relay, to support all my fellow athletes and all my other colleagues within Team GB. It is a very proud day and I thank the selectors for the confidence and faith they have placed in me."
Meanwhile, Jessica Ennis and Christine Ohuruogu lead the charge for the women's Team GB, and Ennis said that competing in front of a home crowd would be like no other event.
"I am really excited to have made my first Olympic team, and cant wait to compete in London on the 3rd & 4th August in front of a home crowd," she said.
"I have been training really hard and feel in great shape and am really looking forward to competing - I know the atmosphere will be amazing!"
