West Ham United are facing questions over their new stadium, after it emerged that the club donated £12,500 to the Conservative Party.

The Taxpayers' Alliance said this raises "serious questions" over the "dubious stadium deal", while a Labour MP said it was inappropriate.

The money, listed in the Electoral Commission's register this week, was given on January 14.

The Premier League team's vice-chairman and Tory peer, Karren Brady, attended the party's annual black and white Ball with club co-owner David Gold a month later.
