The British Olympic Association (BOA) has today announced 71 track and field athletes to compete for Team GB at the London 2012 Olympic Games.
These athletes join the six marathon runners earlier selected to complete the Team GB athletics line-up, bringing the athletics total to 77, and the overall number of athletes selected to Team GB to 502 from across 25 sports.
One of Great Britain's brightest medal prospect, Jessica Ennis described her delight at making her first Olympic team.
She said: "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.
"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."
Dwain Chambers has been selected to represent Team GB at the London 2012 Olympic Games.
The 34-year-old is able to compete after the British Olympic Association's policy of lifetime bans for drug cheats was overturned.
In 2003, he was given a two-year ban from the sport after testing positive for the drug THG.
The selectors took into account the 'A' times he ran last summer, which put him in contention for a spot on the team.
"It is a real honour to be selected as part of Team GB today. For me representing my country in an Olympics is a privilege that should never be taken for granted," said Chambers, who is set to compete in the 100m and 4 x 100m events in London.
