Cabinet Secretary Sir Jeremy Heywood has denied he was responsible for delays in the publication of the Chilcot report into the Iraq war and said the enquiry has received every government document it asked for. Earlier this month, Sir John Chilcot said the report would not be published until after the election.

Sir Jeremy told the Public Administration Committee there had been disagreements between government departments and the enquiry on whether certain very sensitive documents - the publication of which would never previously have been contemplated - should be published.

Deputy prime minister Nick Clegg says his party is going to do "much, much better" than pollsters and critics have predicted.

In a TV interview, Mr Clegg criticised both the Conservatives and Labour, saying: "You've got the Conservatives haring off to the right now, saying they are going to cut, cut, cut, way beyond what's necessary. You've got Labour saying they are going to borrow more money than is necessary. We, the Liberal Democrats, will cut less than the Conservatives, borrow less than Labour, because that's the way you get the right balance - you create a stronger economy and a fairer society."

Two polls published overnight gave the Liberal Democrats 7% or 8% of the vote.
