Under the terms of the Brexit trade deal, boats from France and the rest of the EU can still fish in British water but over the next five-and-a-half years a quarter of their quota will be handed over to the UK.

Talk of naval vessels being dispatched to deal with any clashes in fishing grounds if a trade deal was not agreed with the EU were floated in the run up to New Year's Day and, despite reaching a settlement, the boats still left Portsmouth at the end of 2020.
