French fishing industry representatives have threatened to block the port of Calais and stop exports to the UK in the run-up to Christmas, in the escalating dispute over fishing rights.

French fishermen say they feel deceived by the UK Government for failing to grant them enough post-Brexit fishing licences to access British waters.

“As far as French fishermen in northern France are concerned, in the absence of any results, the blocking of the port of Calais and exports to the United Kingdom for the period leading up to Christmas is an option,” said Olivier Lepretre, president of the powerful fishing committee for the northern Hauts-de-France region.

French fury was sparked after the Government in London announced last month that it had approved just 12 of the 47 applications it had received from French small boats.

Those denied licences were unable to prove a track record of fishing activity in the six-to-12 nautical mile zone in the years before the UK’s departure from the EU, according to a UK Government spokesman.

But the Hauts-de-France fishing committee said the French have worked “meticulously” to provide that evidence, calling the British allocation an “unacceptable decision” on Tuesday.

Mr Lepretre’s threat came a week after he held talks with French maritime minister Annick Girardin, who has asked the European Commission for possible retaliatory measures.

Ms Girardin met virtually with France’s Europe minister Clement Beaune and MEPs Pierre Karleskind and Nathalie Loiseau to “defend the rights of our fishermen”, according to a Wednesday tweet by Ms Loiseau.

“They don’t have to pay the price for #Brexit,” she posted, pledging “calmness, firmness and determination”.

A day earlier, Mr Beaune said France would “take European or national measures to exert pressure on the UK”, and hinted that Britain’s imported energy supply could be disrupted in retaliation for a lack of access to UK waters.

The UK’s Brexit minister, Lord Frost, said it was “unreasonable” to suggest the UK was acting in bad faith when it came to allocating post-Brexit fishing licences to French boats, accusing France of being disingenuous over the UK’s position on fishing access.

“We have been extremely generous and the French, focusing in on a small category of boats and claiming we have behaved unreasonably, I think is not really a fair reflection of the efforts we have made,” he told a Conservative Party conference fringe event on Tuesday.

“The Government has this year issued a large number of licences to EU vessels seeking to fish in our exclusive economic zone (12-200 nautical mile zone) and our territorial sea (six-12 nautical mile zone),” a UK Government spokesman told the PA news agency.

The spokesman added that the approach had been “fully in line” with the UK’s commitments in the Trade and Co-operation Agreement (TCA) agreed as part of the Brexit divorce deal.

Deputy Prime Minister Dominic Raab said the UK will be “calm but resolute” in the row.

“Of course, what the French need to adjust to is the new reality as we have left the EU, we have got a free trade deal – it includes scope on fishing but they can’t expect to have the kind of quotas they had previously, unlimited access,” he told TalkRadio on Wednesday.

The cross-Channel tensions over fishing have been long-running, with earlier rows leading to Navy ships being scrambled to Jersey amid concerns of a blockade of the island.

It is also not the first time the French have used the energy supply threat to try to gain ground in the Brexit row.

In May, Ms Girardin warned that France was ready to take “retaliatory measures” after accusing Jersey of dragging its feet over the issuing of licences to French boats under the terms of the UK’s post-Brexit trade deal.

Jersey gets 95% of its electricity supply from France, with just under half of the UK’s electricity imports, as of 2020, coming from the same source.
