Brexiteers have long hailed the “sea of opportunity that awaits British fishermen and women after the UK leaves the EU but now it has emerged that their boats will be monitored by a French company.

The business that won the tender to track UK fishing vessels wherever they operate, as well as foreign-licensed boats in British waters, is Collecte Localisation Satellites (CLS), a French maritime surveillance provider.

The contract was awarded by the Department for Environment, Food and Rural Affairs (Defra) in late summer having previously been held by a British firm, Globavista.
