I can't imagine that David Cameron is making many friends among the union movement at the moment - and I don't suppose that this is worrying him overly. But he appears to be falling out with his own right wing over the same issue.
Tim Montgomerie, on Conservative Home, is annoyed that Cameron appears set to continue the union modernisation fund.
With the unions pumping £25 million into Labour's election efforts, Montgomerie argues that there is enough cash to spare in the union coffers that they don't need Government funds.
UPDATE 23-3-2010 - Cameron has confirmed in his press conference today that he will continue with the Union Learning Fund and not the modernisation fund
