The Arnie Graf visa row is simmering below the surface. James Forsyth reports in this week’s Spectator:

“It would be wrong, though, to think of Labour as a totally happy ship at the moment. There is the row over the visa status of Arnie Graf, the American community organiser and a close ally of Miliband. Graf’s friends think rivals inside the Labour machine deliberately leaked the news that he had no work permit in an effort to undermine him. Miliband’s confidants, by contrast, think the leak was designed to embarrass Iain McNicol, who as the party’s general secretary might would be hurt most by any administrative failure.”

Poor McNicol is running out of friends, fast.
