Bradley Wiggins Tour win would be pinnacle - Chris Boardman

Former cyclist Chris Boardman says he never thought he would see a British rider win the Tour de France, with Bradley Wiggins on the verge of victory.

Only an accident could stop Wiggins from finishing Sunday's final stage in Paris to become the first Briton to win the race.

Wiggins leads compatriot Chris Froome by three minutes, 21 seconds after beating his Team Sky team-mate in Saturday's time trial.
