French fishing crews are threatening to block French ports and traffic under the English Channel on Friday to disrupt the flow of goods to the UK, in a dispute over post-Brexit fishing licenses.
Fishing crews are expected to use their boats to block ports in Calais, Saint-Malo and Ouistreham, and to use cars to block the highway leading to the tunnel beneath the Channel.

French fishermen are angry at the British government for not granting more licenses to fish in UK waters — and angry at their own government for not doing more to defend them.

But Paris says dozens of French boats have had their applications to fish the UK's rich waters rejected, an assessment strongly contested by London.

But analysts say Macron is keen to take a hardline against Johnson as he eyes re-election in a 2022 poll while the British premier is also keen to talk tough in the wake of Brexit.
