May holds emergency call with Cabinet
The Prime Minister was set to address the Commons at 3.30pm after the emergency call with her ministers on Monday morning.
Just minutes after a Downing Street spokesman insisted the vote would go ahead, the Bloomberg news agency and the BBC cited sources as saying that Tuesday's vote had been cancelled.
Speculation had mounted that the vote on the Withdrawal Agreement could be postponed or scrapped in the face of an open revolt by Conservative MPs and fierce opposition from other sides of the House.
