What the outcomes mean for PM
DEFEAT BY MORE THAN 200 VOTES
Would raise serious questions about Theresa May’s future. Her opponents are holding talks on how to ensure the biggest vote against her.
MORE THAN 150
Would still be one of the biggest defeats any government has suffered in modern British history and could put the Prime Minister’s future in doubt.
FEWER THAN 100
Could leave the Prime Minister appearing to have fared better than expected and enable her to bring the deal back for a second vote. This strategy could be bolstered if she were to secure concessions from Brussels, giving her a justification for tabling another vote.
FEWER THAN 50
Would be even more encouraging for those who want the Prime Minister to allow MPs to vote on the deal again.
Unlikely. If Mrs May pulled it off, it would be considered a great political coup.
