Picture 56 The FT's Jim Pickard got there first and now The Sun reports:

"Labour Chief Whip Nick Brown was accused of a festive smear last night over a snap of Lib Dem leader Nick Clegg in fancy dress on his Christmas card. The photo shows Mr Clegg aged 22 dressed as Ziggy Stardust – complete with a spiky red wig and face paint. Underneath, the card mockingly says: "I want to be Prime Minister."

But Mr Clegg said: "Both myself and Nick Brown have good reason to be embarrassed. I posed for pictures in ridiculous fancy dress 20 years ago – and he is an MP for the Labour Party."
