Fishing remains a "major bone of contention" in post-Brexit discussions, British Foreign Minister Dominic Raab said on Sunday, at a critical stage in discussions.

"I think we have a reasonable position, there is a deal to be found," he told Sky News, noting "progress towards greater respect for the UK position".

But fishing remains "a major bone of contention", he said, repeating that as an "independent coastal state" the UK must "have control of its waters".

Discussions resume Sunday between European and British negotiators Michel Barnier and David Frost.

"The work continues, even on a Sunday," Barnier told reporters in the morning.

There are only a few days left in London and Brussels to try to conclude a free trade agreement ready to enter into force on January 1, at the end of the transition period which has been running since January 31, the official date of Brexit.

In the absence of an agreement, trade would be carried out according to the rules of the World Trade Organization (WTO), synonymous with quotas and customs duties.

Such a scenario would expose both parties to a new economic shock, which would come on top of that caused by the coronavirus epidemic.

According to European sources, Michel Barnier has proposed that the EU return 15 to 18% of the total European quotas fished in British waters and symmetrically recover the quotas fished by the British in the Atlantic and in the Bay of Biscay.

But a government source, quoted by the British agency PA, called these figures "laughable", saying that Europeans "know very well that we would never accept that".

"It would appear that the (European) Commission is failing to internalize the magnitude of the changes needed as we become an independent nation," the source said.

"We hope that the EU will bring new ideas, because what we have seen so far is not enough," said a source close to the negotiations quoted by PA, "they must understand that we are not going to sell our sovereignty".

On his arrival in London on Friday evening, Michel Barnier declared that he would continue to work with "patience and determination".

Face-to-face discussions resumed on Saturday, after the European negotiator had to isolate himself due to a case of Covid-19 in his team.
