It's been announced. 24 March.
Usually the Chancellor's perogative but there you go.
So election should be 6 May so what sort of manifesto budget will we see?
Whatever Darling has up his sleeves, guaranteed that the budget will not be for the good of the country but for the political good of the Labour party.
Expect to see promises, promises, promises, just enough to take the economic narrative and control it whilst trying to squeeze out the Tories.
Should be fun but be warned, whatever Darling has to say at the dispatch box, there will be his helpers pickpocketing you as you watch.
