UK Royal Navy vessels are patrolling waters around Jersey, amid concerns of a possible blockade of the largest of the Channel Islands, due to an ongoing row with France over post-Brexit fishing rights.

HMS Severn and HMS Tamar have been deployed to "monitor the situation", at the Channel Island, as reports suggest as many as 100 French fishing vessels could protest at the Port of St Helier over the lack of access.

French maritime minister Annick Girardin warned on Tuesday that the country was ready to take "retaliatory measures", accusing Jersey of dragging its feet over issuing new licences to French boats.

British Prime Minister Boris Johnson spoke to Chief Minister of Jersey, Senator John Le Fondre, and Minister of External Affairs Ian Gorst yesterday and "underlined his unwavering support" for the island.

Paris has warned it could cut off power to the island, which receives 95% of its electricity from France through three undersea cables, in retaliation to the fall out.
