Sir Chris Hoy supports BOA's lifetime Olympic ban

Four-time Olympic gold medallist Sir Chris Hoy says the rest of the world should follow Britain and prevent drug cheats from competing at the Olympics.

The British Olympic Association has said it is likely to lose its legal battle with the World Anti-Doping Agency over a by-law that has kept a number of British athletes out of past Olympics.

Hoy also talks to BBC Sport's Matt Slater about the selection policy for Team GB's track cycling squad for London 2012.
