Labour and the unions might well be in a different league to the Tories when it comes to donors buying access, policy and stitching up seats, though that doesn’t mean Dave is not up to his neck in dodgy donations as well. Adrian Beecroft was  in the “premier league” of Tory donors, he gave well over half a million to the Tories since 2006. Beecroft lobbied Cameron on workers’ rights and no-fault dismissal and he even got to write a report on it. Kerching!

Then there is the case of JCB chairman Sir Anthony Bamford, who Cameron personally advised on the process of making a donation.

He was obviously listening: Bamford has donated over £2.5 million in recent years and lent Cameron his helicopter many times. In 2012 Downing Street commissioned a report from him. Bonus!
