In pictures: Experts' predictions for the General Election - 03/05/15 Michelle Harrison (TNS)

“We enter the last few days of this campaign pretty much where we started. This election represents what happens when a country is not confident about its economic future, unsure of its place in the world, and fed up with the state of its politics. “The political stalemate at the centre, and the fragmentation of the traditional party system, has left us with a set of polls incapable of telling what will ultimately happen, when there are so many potential scenarios. What we can feel confident about though is that Thursday will be a seismic night for politics in Scotland. When the votes are counted, we expect the Tories to be the largest party, but that Labour should still have the greatest chance of forming a government. But how do we measure the advantage for the Conservatives of already being in No 10 in the days after the general election? The real drama will start on Friday.”
