Rance has been accused of making “disproportionate” threats to cut Jersey electricity in a new post-Brexit fishing line.
The Channel Island has been accused by Paris of dragging its feet on licensing French boats as part of the UK-Brussels trade deal after Brexit.
French Minister of Maritime Affairs Annick Girdardin warned on Tuesday that France was ready to take “retaliatory measures”.
She said: “We are ready to use these retaliatory measures. Europe, France has the means – it is written in the agreement.
“As far as Jersey is concerned, let me remind you, for example, of the transmission of electricity by submarine cable. So we have the means. Although I would regret getting to this point, we will if we have to.
These remarks led the Minister of Foreign Affairs of Jersey to accuse France of making “disproportionate” threats.
Senator Ian Gorst said such action would not be warranted after the island said it would require boats to submit more details before licenses can be granted.
“This is not the first threat the French have made to Jersey or the UK since we entered into this new deal,” he told UKTN Radio 4 Today.
“It would seem disproportionate to cut off the electricity to need to provide additional details so that we can refine the licenses.”
Mr Gorst said he believed the dispute could be resolved amicably, adding: “I think a solution can be found. I am optimistic that we can allow more time to allow this evidence to be provided. “
About 95% of Jersey’s electricity comes from three submarine cables from France, according to Jersey Electricity, with the remainder supplied by diesel generators on the island.
On Friday, 41 vessels were cleared by the UK to fish in waters off Jersey – however, France said that clearance was accompanied by new requests “which have not been settled or discussed, and of which we were not informed “.
Meanwhile, a government minister said the EU and UK must “fix” any issues.
Speaking on Sky News, Vaccines Minister Nadhim Zahawi said: “I think my very strong feeling about this is that we have to work constructively.
“It is a problem for the commission to work with our team and all the indications of the minister [David] Frost and his team believe that the commission takes seriously some of these operational challenges that we must solve together.
A spokesperson for the UK Department for Environment, Food and Rural Affairs said: “We are working closely with the EU and the Jersey government on arrangements for access to fisheries after the end of the transitional period for the granting of licenses. “
