Iain Dale was listening to Hattie Harperson, being interviewed by Stephen Nolan on '5 Live'.
Amongst the torrent of lies, distortions and untruths, he spotted that..
"..she guaranteed that over the lifetime of a Parliament no public sector worker would get a pay cut"
As Ma Dale points out:
"She has no power to do that, it wasn't in the Labour Party manifesto .. Alistair Darling will be absolutely fizzing with fury."
Well, Iain, she might have 'no power' to make policy, but she has all the power she wants to tell lies. In all likelihood, this is just yet another little fib. It's not in the manifesto because its not fucking true.
However, what can the other parties do?
If they talk about it, draw attention to it, point out that it's probably a porky, there'll be an instant cry of "Oh, so they won't guarantee it? They will cut public sector pay! Look, everybody, the eevil Tories / eevil Lib Dems are promising to cut public sector pay. Ewwwwww!"
If they don't mention it, then yet another Labour lie sinks into the minds of their core voters.
And that's how they work.
