Who's winning the donations race? Political donations for the final quarter of 2011 were published today and the chart below shows how the parties fared.

But where's the money coming from? The ten biggest donors are listed below, with the notable inclusion of the Ministry of Sound, which donated £153,267 to the Liberal Democrats. The club's owner, James Palumbo, is a regular donor and a long-standing friend of deputy leader Simon Hughes. As he told the NS in September 2011:

I'm helping the Lib Dems. I've known Simon Hughes for years - he is our local MP in Southwark, a great guy. There are various ways I can be helpful, in terms of systems, particularly marketing, which we're very strong on, and IT and HR. I'm doing a bit of work for them and seeing how that goes. But it's new to me. It's a different language. It's a different set of rules.

Meanwhile, Labour's dependence on the unions continues. The latter were responsible for 76 per cent (£1.8m) of all donations in the last quarter, with the GMB (£649,092) and UNISON (£427,774) the biggest contributers.
