PRO-EU Speaker John Bercow has tried to wreck Theresa May's Brexit plans yet again today as he blocked one of her lifelines to get the deal over the line.

This morning the Speaker dealt a further blow to her chances of getting an agreement as he refused to allow any amendments to woo Labour.

Labour MPs Gareth Snell and Lisa Nandy put forward a plan to give Parliament more say in the next stage of Brexit talks.

It would have allowed MPs to set the negotiating mandate for talks, something usually the PM would only have the power to set.

The amendment could have given Labour MPs in Brexit constituencies enough of an excuse to back the deal as not to anger their voters.

Their numbers could have been one way to make up for the 10 DUP MPs who are still refusing to get behind the PM.

But at the start of today's debate Mr Bercow said he wouldn't allow any votes on any amendments - potentially torpedoing the PM's hopes of finally pushing her deal over the line.

Attorney General Geoffrey Cox did tell the Commons he would have accepted the Labour plan, which could still be enough to sway some Labour MPs in Brexit constituencies over.

Mr Snell, whose Stoke on Trent constituency voted Leave, later said he was "minded" to vote for the deal on the basis of his promises.

Fellow Labour Leaver John Mann told The Sun this week that 35 MPs could be ready to back the PM's Brexit deal and halt the chance of a second referendum.

MPs will vote for the third time on the PM's deal later today - on the day Britain was supposed to be leaving the EU.

At around 2.30pm they will only cast their ballots on the withdrawal agreement, as the political declaration has been ditched in order to make it different enough to pass Speaker Bercow's test.

Last week he threw another spanner in the works by refusing to let the Government bring back the deal a third time as it was too similar to the last one.

MPs have repeatedly accused him of being biased over Brexit - and his wife even has a 'Bollocks to Brexit' sticker on her car.

The PM was given a glimmer of hope as more and more Tories came over to her side today ahead of the crunch vote.

Hardliner Dominic Raab is the latest big beast to fold and say he will back her.

Boris also confirmed this morning he will definitely vote for the deal too.

If the deal fails today then it opens the door to a soft Brexit next week - which is likely to be a customs union.

Remainer rebels will try and force the PM to go for their plan, which she's already rejected as it would divide the party.

Mrs May has said she will resign if her deal is passed, but if it fails then she could stay in power for months or years to come.
