The former prime minister discusses his second election victory, after which he built a close relationship with President George Bush. When terrorists struck the US on 9/11, he took a leading role in building support for the US-led war in Afghanistan.

He talks to director Michael Waldman about the decision to go to war in Iraq, which many see as his greatest mistake.
