Boris Johnson and European Commission President Ursula Von Der Leyen will seek to break the stalemate over a post-Brexit trade deal on Saturday.
Negotiators for the two sides called in the two leaders after saying “significant divergences” remained following a week of intensive talks.
Time is running out to get a deal through before the UK leaves EU trading rules on 31 December.
Most of the deal has been completed but key sticking points remain.
These include fishing rights, the rules governing state subsidies for business and how the agreement is policed.
