One thing I forgot to mention in the earlier post about Harriet Harman's interview with Stephen Nolan is that she guaranteed that over the lifetime of a Parliament no public sector worker would get a pay cut. To me this is the biggest gaffe of the election campaign so far. She has no power to do that, it wasn't in the Labour Party manifesto and Alistair Darling will be absolutely fizzing with fury.
Will the Conservatives take Harman to task over this? Probably not, because they know that they will then be accused of wanting to cut public sector pay themselves.
So Harman will get away with it.
