May is set to update parliament on her latest meetings in Brussels and Dublin aimed at securing a divorce agreement with the EU, with Britain due to leave the bloc on 29 March.
In January, MPs overwhelmingly rejected the deal struck between May and Brussels and the British premier has since been attempting to secure changes that would satisfy parliament’s lower House of Commons.
Brexiteer MPs in her Conservative Party are particularly unhappy with the so-called backstop provision intended to keep the border with Ireland free-flowing.
Some fear it could leave Britain trapped in the European Union’s trade rules with no unilateral way out but would back a deal if the backstop was time-limited or replaced with alternative arrangements.
“We now all need to hold our nerve to get the changes this house has required and deliver Brexit on time. By getting the changes we need to the backstop; by protecting and enhancing workers’ rights and environmental protections and by enhancing the role of parliament in the next phase of negotiations I believe we can reach a deal that this house can support,” May is due to tell MPs.
Brexit Secretary, Stephen Barclay and David Lidington, May’s de facto deputy are in Strasbourg meeting members of the European Parliament, while British Foreign Secretary Jeremy Hunt is in Paris as part of a diplomatic offensive.
The European Union’s (EU) chief Brexit negotiator, Michel Barnier, has called for “clarity and movement” from Britain.
In an effort to break the impasse, Barclay hosted Barnier for a working dinner at the British ambassador’s residence in Brussels late Monday, with concern growing on both sides of the Channel.
“We are clear from our side that we are not going to reopen the withdrawal agreement, but we will continue our discussion in the coming days,” says Barnier.
