Labour MPs have been forced to call in the police over death threats in the last 48 hours after they refused to back Jeremy Corbyn, The Telegraph has learnt.

Vicky Foxcroft, a Labour whip, received a call to her constituency office which said: “If she doesn’t support Corbyn I will come down to the office and kick the f*** out of you.”

Police officers had to rush her office, close the shutters and attempt to trace the call after the man said he was on his way and hung up.
