The Sunday Times chief sports writer spent 13 years battling to prove that Lance Armstrong was a drugs cheat. Watch live as he tells his story.

The disgrace of Lance Armstrong, serial winner of the world's toughest bike race and iconic figure to the cancer community, was the biggest sports story of the year.

Now everyone has the chance to hear David Walsh, Sunday Times chief sportswriter and recently awarded British Journalist of the Year and Sports Journalist of the Year at the British Journalism Awards, tell of his 13-year battle to prove that Armstrong was a drugs cheat.

The Times+ event - hosted by Sunday Times News Review Editor, Alan Hunter - is completely sold out, but Times+ is celebrating David's recent awards by streaming live the whole discussion so that all readers can watch it.

Readers can join him at 7.45pm on Thursday December 13 to see all the action from the comfort of their own sofa - and they can even ask David a question on the night by using the hashtag #WalshLive to contact The Sunday Times via Twitter.
