Never say never when negotiating with the European Union, UK Foreign Secretary Dominic Raab said as London and Brussels are engaged in last-minute talks over the future of their trade relationship post-Brexit.

He noted that London would need to see "substantial movement" by Sunday - the day picked by Prime Minister Boris Johnson and President of the European Commission Ursula von der Leyen as a final deadline for a Brexit deal. At the same time, Raab said that real progress needs to be made for the negotiations to continue beyond the Sunday deadline.

Raab recognized that if the two sides fail to reach an agreement, there will be "bumps along the road", including potential changes in food prices.

According to him, significant differences remain, mainly around fisheries and certain regulatory requirements, but there's clearly scope to continue the talks. He, however, emphasized that Britain was not going to "sacrifice basic points of democratic principle" in order to get a deal.

He went on to note that irrespective of the differences, "movement needs to happen" on both issues, fishing quotas and level playing field, by Sunday. Regarding the latter, he noted, the European bloc has of late hardened its position.

During a discussion on Wednesday, Boris Johnson and Ursula von der Leyen agreed that a firm decision should be taken by Sunday concerning the future of the Brexit talks, despite "very large gaps" between the UK and the EU.

Von der Leyen later took to Twitter to say that while the parties "gained a clear understanding of each other’s positions, they remain far apart".

Earlier in the day, Johnson addressed MPs about the prospects of post-Brexit arrangements with the EU, asserting that "a good deal is still there to be done". The prime minister thundered that no British PM would sign up to the demands the European Union is "currently insisting on", adding that while there is a trade deal to be done, the country would equally prosper without one.

"Our friends in the EU are currently insisting that if they pass a new law in the future with which we in this country do not comply ... then they want the automatic right ... to punish us and to retaliate", he said in parliament.

While the post-Brexit trading and governance arrangements remain in limbo, despite heated talks in London, last week, the British side reportedly accused Brussels of revising their conditions at the eleventh hour, which, officials said, would certainly further threaten any potential compromise.

In light of the tight time framework still allocated for a deal to arrive - before the transition period expires on 31 December - concerns have arisen that the sides might enter the new year without an agreement.
