Labour MP Tom Watson has quit his job in the Shadow Cabinet to "speak out in areas of public interest."

In an open letter to Ed Milliband, the MP finished with: "John Humphrys asked me why you were not at Glastonbury this weekend. I said Labour leaders can't be seen standing in muddy fields listening to bands. And then I thought how terribly sad that this is true. So: be that great Labour leader that you can be, but try to have a real life too. And if you want to see an awesome band, I recommend Drenge."

Watson has previously campaigned for other music related policy including the Digital Economy Act and last year's Live Music Act.
