In the fisheries dispute, the French government is increasing the pressure on Great Britain.
From November 2, British fishing boats will no longer be allowed to dock at certain French ports, as the Paris Ministry of the Sea announced on Wednesday evening.
In addition, France will systematically check the safety of British boats in the future.
Trucks driving from France to Great Britain or in the opposite direction should therefore also be checked more closely.
For the future, further measures would be worked out, it said from the ministry.
It is also not ruled out that the French electricity supplies to the island are fundamentally reconsidered.
The background to this is a dispute over fishing licenses.
Paris accuses London of still not having granted all licenses after ten months of intensive talks.
In the Brexit agreement it was agreed that European fishermen should get fishing licenses for a zone of six to twelve nautical miles off the British coast.
In order to obtain a license, a fisherman must prove that he was previously active in these waters.
There has long been a dispute between France and Great Britain over the implementation, also in the area of the Channel Islands Jersey and Guernsey.
