Theresa May and Jeremy Corbyn have called talks to break the Brexit deadlock in Parliament “constructive”.
The two leaders met on Wednesday afternoon and agreed a “programme of work” to try to find a way forward to put to MPs for a vote.
It is understood that each party has appointed a negotiating team who will meet later tonight ahead of a full day of discussions on Thursday.
A spokesman for No 10 said both sides were “showing flexibility and a commitment to bring the current Brexit uncertainty to a close”.
