This weekend on BBC World's Great Britons series, Mo Mowlam presents the story of former British Prime Minister Winston Churchill's life. A case will be made as to why Churchill deserves to be voted the Greatest Briton in the international poll being conducted by the broadcaster.

The show airs on 2 August at 7:40 pm with a repeat on 3 August at 2:40 pm and 11:40 pm.

Churchill found the destiny he had marked out for himself as Prime Minister from 1940 to 1945. His colleagues admired his courage and vision, but were exasperated by his irregular working habits. In fact HBO last year made a film The Gathering Storm that dwelt on Churchill's life. Programme presenter Mowlam was a member of the UK government and Tony Blair's Cabinet until the general election of June 2001. She has been Secretary of State for Northern Ireland and later Minister for the Cabinet Office and Chancellor of the Duchy of Lancaster.
