26 March 2013 Last updated at 23:42 GMT

The former foreign secretary, David Miliband, is planning to leave Parliament to move to the US to work for a charity, a close friend has confirmed to the BBC.

Mr Miliband, 47, was beaten to the Labour leadership in 2010 by his brother Ed.

The South Shields MP has taken a back seat since, opting not to join his brother's shadow cabinet.

There had been widespread rumours that he was set for a return to the opposition front bench, with Ed Miliband insisting recently that "the door is open".
