Prime Minister Boris Johnson has been defeated in his first Parliamentary vote, as MPs voted in favour of trying to block no deal.

328 MPs voted in favour of a bill, a majority of 27, demanding that Johnson ask for an extension to Article 50 if he is unable to agree a new deal with the European Union by October 17th.

This is the first time since William Pitt the Younger in 1783 that a Prime Minister has lost their first Parliamentary vote.

21 Conservative MPs rebelled against the government and voted for the motion, including former Chancellors Ken Clarke and Philip Hammond, and former leadership contender Rory Stewart.

Number 10 have confirmed that all 21 have had the whip withdrawn.

In the wake of the result, Johnson said that he has tabled a motion for a snap general election.

For this to succeed, this would require a two-thirds majority in the House of Commons under the Fixed Term Parliaments Act.

Jeremy Corbyn, leader of the Labour Party, said that he wants to get the bill through Parliament first to “take no deal off the table” before considering a snap election.

The vote comes just hours after the Conservative-led government lost its working majority in the House of Commons, after another Conservative MP defected from the party to join the Liberal Democrats.

The Conservatives now have only 289 seats in the House of Commons.
