The UK is “ready to welcome the EU team” to continue negotiations over a post-Brexit trade deal, says No 10.
The two sides’ chief negotiators, Lord David Frost and Michel Barnier, spoke on the phone earlier after talks stalled last week.
After the conversation, Downing Street said the pair had “jointly agreed a set of principles for handling this intensified phase of talks”.
They warned it was “entirely possible that negotiations will not succeed”.
The statement added: “It is clear that significant gaps remain between our positions in the most difficult areas.
“But we are ready, with the EU, to see if it is possible to bridge them in intensive talks.”
Both the UK and EU are calling on each other to compromise ahead of the looming December deadline for a deal.
Key areas of disagreement between the two sides include fishing rights and post-Brexit competition rules.
