General election 2015: Parties row over who pays for pledges

A bitter row has broken out between the two main parties over how much the next government will cost.

The Conservatives say there will be chaos if Ed Miliband becomes the next prime minister, accusing him of making billions of pounds of unfunded pledges.

Labour describes this as a political smear and insists its plans are fully funded. Ed Miliband said the party was offering "hope not falsehoods".
