Former British Prime Minister, Tony Blair, has taken on the author and renowned atheist Christopher Hitchens in a debate on the value of religion.

Mr Blair, a convert to Catholicism, was arguing in favour of the motion "Religion is a force for good in the world" in the Munk Debate in Toronto.

Mr Hitchens, who is undergoing treatment for cancer, proposed that religion is the world's "main source of hatred".
