2021 Jersey dispute

In 2021, a dispute erupted between French fishermen and the Government of Jersey about the licensing of French fishing boats to fish in Jersey's territorial waters. Jersey is a British Crown Dependency, and despite not being part of the United Kingdom, the licensing of European Union fishing boats to fish in Jersey's territorial waters has changed after the UK exit from the EU. On 6 May 2021, French fishermen held a protest in the waters off Jersey's main harbour. The UK is responsible for the defence of the Channel Islands and sent two patrol boats to Jersey in response to the fishermen's threats to blockade it. French politicians suggested that Jersey's electricity supply fed by undersea cables from France could be cut off in retaliation for Jersey placing limitations on the extent to which French boats can fish in the island's waters.

As of March 2022^[update], 131 boats had received permanent licences. Jersey considered the dispute to remain a live issue and were awaiting any formal complaint that France may lodge with the European Commission. The Jersey government continued to hold off enforcing some of the conditions of the French fishermen's licences, but intended to revisit them.
