British negotiators expect to clinch a deal on Brexit transition terms as early as this weekend following a series of climbdowns to secure a deal from the EU, the Telegraph understands.

Sources on both sides of the negotiation said there were now no insuperable sticking points in the negotiations over a deal that would provide a largely status-quo transition until at least December 31 2020.

Negotiators are scheduled to work throughout the weekend in a bid to finalise a legal text for the 21-month agreement that will be hailed by Downing Street as a significant win for Theresa May, and a key stepping-stone on the road to Brexit.

David Davis, the Brexit Secretary, who this week told the Commons he was “confident” a deal would be secured, will be in Brussels over the weekend and is scheduled to have a meeting with his EU counterpart, Michel Barnier, on Monday.

There still remain concerns that Ireland might yet scupper a deal at the eleventh hour over demands that Mrs May make “more progress” on the question of the Irish border.
