Sir Bradley Wiggins has defended his use of powerful steroid injections to treat asthma and allergies before three big races.

Computer hackers leaked his confidential medical records two weeks ago, showing he was given official permission for the jabs, including before the Tour de France in 2012, which he won.

Bradley Wiggins wasn't specifically asked about those questions in depth during his interview with Andrew Marr and that he insists he has stayed within both the letter and the spirit of the laws.
