The UK and EU have agreed to carry on post-Brexit trade talks after a call between leaders earlier on Sunday.

In a joint statement, Boris Johnson and European Commission President Ursula von der Leyen said it was "responsible at this point to go the extra mile".

The pair discussed "major unresolved topics" during their call.

The two sides had said Sunday was the deadline for a decision on whether to continue with talks, with the UK set to leave EU rules at the end of the month.

The leaders agreed to tell negotiators to carry on talks in Brussels "to see whether an agreement can even at this late stage be reached".

They did not say how long these latest talks would continue, but the ultimate deadline is 31 December, and time must be allowed for the UK and European Parliaments to vote on any deal that emerges before then.

Mrs von der Leyen said Sunday's call with Mr Johnson had been "constructive and useful".

But Mr Johnson repeated his warning from earlier in the week that a no deal scenario was "most likely".

The UK and EU have been carrying out negotiations for a post-Brexit trade deal since March and are attempting to secure one before the so-called transition period end on 31 December - when the two sides would move to trading on World Trade Organization (WTO) rules.

Without a trade deal, tariffs - charges on goods being bought and sold between the two sides - could be introduced and, in turn, prices on certain products may go up.

Reading out the joint statement, Mrs von der Leyen said: "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."

Mr Johnson later said "where there is life, there is hope", and that the UK "certainly won't be walking away from the talks".

But he added: "I've got to repeat the most likely thing now is of course that we have to get ready for WTO terms.

"As far as I can see, there are some serious and very difficult issues that currently separate the UK from EU and the best thing to do now for everybody… [is to] get ready to trade on WTO terms."

Labour's Rachel Reeves welcomed the continuation of the talks and said the worst outcome would be to "crash out with no deal whatsoever on 1 January".

She added: "I hope that they [the talks] will swiftly conclude, but I also hope on behalf of all British businesses and workers, and our security as well, that the government deliver the promise they made to the British people and come back with a deal." (Text, excluding headline, courtesy BBC)
