Brexit Plan B: When will Theresa May reveal her new proposals to MPs? What can we expect?

Theresa May is set to unveil her latest Brexit plans to Parliament in a desperate attempt to break the Commons deadlock.

The embattled Prime Minister will reveal her "Plan B" before MPs on Monday as she tries to overturn last week's humiliating defeat.

There are signs the new deal won't be radically different from the last, save for concessions made on the Irish backstop in a bid to win round Tory and DUP MPs.

But the EU has insisted it will not reopen negotiations on the withdrawal agreement, and previously said the contentious backstop "must remain" a part of the deal.

When will Theresa May reveal her Plan B?

Mrs May is required to present her "Plan B" to Parliament on Monday, January 21 thanks to an amendment tabled by Dominic Grieve.

She is scheduled to brief the House of Commons on how she plans to proceed with Brexit on Monday afternoon.

Mrs May will make oral and written statements to the House explaining how she intends to proceed, and will table a "neutral" motion that will be debated.

MPs will debate the deal, and any amendments, on January 29. The vote is not expected until later on in the evening of that day.

What can we expect from Theresa May's Plan B?

Signs have suggested Mrs May's new deal will not look much different to the old plan which was rejected by Parliament last week, and there is lttle expectation she is ready to offer concessions that could win over opposition MPs.

But it is believed she will try to resolve concerns over the sticking point of the Irish backstop, which is aimed at avoiding a hard border with Northern Ireland.

It is not clear how she will do this, with the EU insistent on it remaining part of the withdrawal agreement.

It has been reported that Mrs May had planned to press Brussels for changes and concessions to the backstop.

Other ideas suggested Mrs May has considered removing the backstop from the agreement entirely, and replacing it with an Anglo-Irish treaty.

But both of these had been flatly rejected by the EU.

The Daily Telegraph reported early on Monday that Mrs May was even condering trying to amend the Good Friday Agreement, although this was described as a "non-starter" and denied by No10.

Mrs May's spokesman said on Monday that her Brexit deal would have to change to win parliament's support.
