On Thursday, eight members of the cabinet - including the Brexit secretary, Steve Barclay and leader of the house Andrea Leadsom - voted against Mrs May's ultimately successful motion to extend article 50.
Speaker of the House John Bercow was criticised by a number of Conservative Brexiter MPs for not selecting any of the amendments which would categorically rule out a second referendum; although, as he pointed out, any MPs strongly opposed to a second referendum could vote against Amendment H without difficulty.
The Prime Minister has said the delay only be until June if Parliament passes her deal - or a much longer one if they reject it a third time.
Protesters plan to set out Saturday from Sunderland, which is 270 miles (434 kilometers) north of London that voted by 61-39 percent in 2016 to leave the EU.

Sterling has rallied 1.7 percent against the dollar this week after British lawmakers voted against leaving the European Union without a deal and backed a delay to the March 29 exit date.
One further complication is that due to United Kingdom parliamentary rules the Speaker John Bercow could decide there should be no further debates and votes on Mrs May's deal as it has already been rejected and is not likely to have changed in any way by next week. May's spokesman said the government was still making preparations for a no-deal exit.
A cross party amendment from Labour's Hilary Benn and Yvette Cooper with Tory Oliver Letwin cancels Government business next Wednesday and sets the stage for "indicative votes" meant to identify what kind of Brexit could pass the Commons.
The UK Government would have to take further steps to stop that happening. Either she'll have to go to get her Brexit deal through or they'll be a vote of confidence'.
