Labour deputy leader Tom Watson given £500,000 in donations from Max Mosley

Tom Watson has received donations worth £500,000 from Max Mosley in less than a year.

The latest official records show Mr Watson this month registered a donation worth £300,000 received via the Labour Party to support his office as deputy leader and shadow culture secretary from the former motor racing boss.

It follows a similar donation from Mr Mosley to Mr Watson registered last June worth £200,000.

Mr Watson said: "I'm proud to call Max Mosley a friend and I'm delighted he has made a financial contribution to Labour.

"His generous donation will help the party develop strong policies for our next manifesto."

Mr Mosley is the primary financial backer of the Impress press regulator which was set up in the wake of the Leveson Inquiry into press ethics.

The Independent Press Regulation Trust agreed to a £3.8 million four-year funding deal for Impress and said this money had been guaranteed by the Alexander Mosley Charitable Trust.

This was set up by Mr Mosley, a victim of a newspaper sting involving images of him at a sex party, with Impress also receiving a "generous" donation from writer JK Rowling.
