Cycling disfigured by doping - Cookson

British Cycling chief Brian Cookson announces his candidacy for president of world cycling's governing body, the Union Cycliste Internationale (UCI).

The 61-year-old says the sport has become "disfigured by doping" as the UCI has been "mired in disputes with other international bodies such as Wada (World Anti-Doping Authority)".

Irishman Pat McQuaid has led the UCI since 2006 but his handling of the Lance Armstrong scandal has weakened his position ahead of September's election.
