Johnson resigns as Shadow Chancellor

James Kirkup is reporting a rumour that Alan Johnson is to resign. More to follow.

UPDATE: He has resigned. Sky News is reporting that Johnson has gone for personal reasons. That may be so – and because of the timing (the government was having the day from hell until ten to five this evening) I suspect that it is – but it will be a hard line to hold, given Johnson’s fraught tenure and his very public disagreements with a leader he didn’t back in the first place. A serious problem for Miliband, then, just as his fledgling leadership was beginning to pick up after Oldham.
