The Final Priministerial Debate

Gordon Brown, David Cameron and Nick Clegg battled it out for the third and final time tonight on BBC at the University of Birmingham, seven days before the general election. It was chaired by David Dimbleby.

This is the first election that has featured such debates and it has totally changed the political landscape in that the Liberal Democrats have become a real force - as a result of a great performance by Nick Clegg.

A hung parliament is almost inevitable. But what has become important, for the first time ever, is the popular vote. The popular vote becomes important in a hung parliament, and because of the current political system we could see the situation where the Liberal Democrats could win the popular vote, but still only have a small relative number of seats in Westminster.
