Week in Westminster - 28/11/2009

A look behind the scenes at Westminster with Steve Richards. A recent shift in opinion poll ratings has raised visions of a hung parliament. The last one in Westminster was in the late seventies, the so-called Lib Lab pact. Jim Callaghan was Prime Minister, Roy Hattersley, now Lord Hattersley, was in his cabinet, and David Steel, now Lord Steel, was the Liberal leader. How do they think it worked? David Cowling, the BBC's head of political research, on the accuracy of political polls. Economists Larry Elliott (The Guardian) and Liam Halligan (Prosperity Capital) examine the political options for handling the economic deficit. Will the inquiry into the Iraq war, now underway, reveal any more than we know already? George Mudie, a Labour MP who regrets his support for the war, and Bernard Jenkin, a shadow defence spokesman at the time, discuss their expectations of the Chilcot inquiry.
