Britain and the European Union are "closing in" on a withdrawal agreement, Brexit minister Dominic Raab said on Friday, ahead of a meeting by European leaders in Salzburg next week.
Britain is due to leave the bloc on March 29 but is yet to reach a full exit deal with Brussels and some rebels in Prime Minister Theresa May's Conservative Party have threatened to vote against any agreement unless she changes her proposals.
Both London and Brussels are hoping to reach a deal by mid-November. May has said next week's informal EU summit will be a "staging post" in the negotiations that will allow the bloc's leaders to discuss her Brexit plans for the first time.
"While there remain some substantive differences we need to resolve, it is clear our teams are closing in on workable solutions to the outstanding issues in the Withdrawal Agreement, and are having productive discussions in the right spirit on the future relationship," Raab said after a phone call with EU chief negotiator Michel Barnier.
"We reiterated our willingness to devote the necessary time and energy to bring these negotiations to a successful conclusion," he said, adding that the pair agreed to take stock again following the Salzburg summit.
Barnier issued no statement and an EU official described the call as having “taken stock of the ongoing negotiations”.
On Thursday the government published a set of advice notices for Britons on how to prepare for the possibility of a "no-deal" Brexit, and May held a meeting of her top team of ministers to discuss the government's plans for leaving without an agreement.
Bank of England Governor Mark Carney told the meeting Britain's property market would crash and mortgage rates spiral up in the event of a chaotic no-deal Brexit, with house prices falling 35 percent over three years, the Times newspaper reported.
The Co-Operative, Britain's sixth-largest supermarket group, said it could not guarantee shortages of some food products would be avoided in the event of a no-deal Brexit.
Pro-Brexit rebels in May's party have become increasingly vocal in their opposition to her Brexit proposals this week, with one former junior minister saying 80 or more of May's lawmakers were prepared to vote against them.
The opposition Labour Party's foreign affairs spokeswoman Emily Thornberry told the Financial Times her party was set to vote against any Brexit deal and the lack of a viable exit from the EU would force May from office before Christmas.
