The British Prime Minister Theresa May is due to hold a conference call with her Cabinet colleagues this afternoon to outline her latest Brexit strategy.
She will update her colleagues on conversations she has had with EU leaders over the weekend and opposition leaders in the UK in recent days.
It comes amid reports that two separate groups of backbench MPs are considering moves aimed at removing the government's power to deliver Brexit.
The separate amendments would block a no-deal Brexit and force the government to extend the Article 50 process.
The first – led by former Tory minister Nick Boles and Labour MP Yvette Cooper – would block possibility of the UK leaving the EU without an agreement about a future relationship.
The second – led by former UK Attorney General Dominic Grieve – would suspend Article 50, delaying Britain’s exit from the EU.
Downing Street has described the reports "extremely concerning" with International Trade Secretary Liam Fox warning there will be a "political tsunami" if the government fails to deliver on leaving the EU.
A Number 10 spokesperson said: “Any attempt to remove the government's power to meet the legal conditions of an orderly exit at this moment of historic significance is extremely concerning.”
“This news should serve as a reminder to those MPs who want to deliver Brexit that they need to vote for it - otherwise there is a danger that parliament could stop Brexit.”
Mrs May is due to deliver her alternative Brexit proposals in a House of Commons speech tomorrow.
