London:British Prime Minister Boris Johnson and European Commission President Ursula von der Leyen have agreed to go the "extra mile" in their pursuit of a post-Brexit trade agreement after they spoke on Sunday, which was seen a hard deadline for the prolonged UK-EU negotiations.
Both sides are hoping for a last-minute "eleventh-hour" compromise in order to have arrangements in place before the Brexit transition period ends on December 31.
However, significant divergences over key sticking points on fishing rights and competition rules have so far proved unsurmountable.
"We had a useful phone call this morning. We discussed the major unresolved topics. Our negotiating teams have been working day and night over recent days," Johnson and Von Der Leyen said in a joint statement after their crucial phone call on Sunday afternoon.
"And despite the exhaustion after almost a year of negotiations, despite the fact that deadlines have been missed over and over we think it is responsible at this point to go the extra mile. We have accordingly mandated our negotiators to continue the talks and to see whether an agreement can even at this late stage be reached," they said.
Johnson has called a meeting of his Cabinet ministers to discuss the latest state of play, which experts hope indicates that some movement is being made possible.
"Even at the eleventh hour, the capacity exists for a deal," urged Michael Martin, the Prime Minister or Taoiseach of Ireland, the country arguably most affected as an EU member-country sharing a border with the UK territory of Northern Ireland.
If the UK and EU are unable to strike a deal, the two sides would be trading on World Trade Organisation (WTO) norms, with considerable barriers to the movement of goods as well as people.
With the UK no longer signed up to the EU rules, it would also mean travel restrictions for Britons travelling to and from the EU at the end of the Brexit transition period on December 31, given the coronavirus pandemic lockdown rules.
The negotiating teams on both sides have been working through the weekend to try and find a way out of the deadlock but UK Foreign Secretary Dominic Raab said on Sunday morning that the "political will" to clinch a deal remains elusive.
