From today's Observer:
"Unite is to give the Labour party £4m to help fund its general election
campaign. The union agreed the deal with the Labour leadership a few
weeks ago as Labour desperately sought the cash to mount an effective
campaign against the Conservatives. The £4m represents half of the
money that the unions have been asked for by Labour. Up to £2m is said
to have been requested from Unison, the public services union, and
another £2m from the GMB general union."
Last week Michael Gove set out the scale of Labour's reliance on the unions and pointed to a number of policy changes that seem to have been granted in return for the cash. And that's before you get to the other quid pro quo of having candidates favoured by the union paymasters getting selected for safe seats – of which there was another example just last night.
