When EU regulations will have been wiped out due to the Brexit, a new legal frame will come into force. The London Convention from 1964 would be an option, but Britain could ignore this one to boost its present situation. "This would allow them to effectively ban any foreign fishermen from their waters, contrary to the London Convention", Lisa Lust, spokeswoman for Bourgeois, told the VRT.

However, Mr Bourgeois was thinking of another option, the charter from 1666. This was discovered in the Bruges archives in 1963. A Bruges alderman next ventured out into British waters to test it out. But while the Belgian dared the British, these decided to let sleeping dogs lie.

"He deliberately had himself arrested by the British hoping they would take him to court. However, this didn't happen. Documents from the British archives later revealed that it was advised against taking the Belgian to court, because of fears concerning the 1666 Charter. They were afraid it would still be in force", explains Lisa Lust.

This being said, Lust admits chances are small the 1666 Charter would still apply, adding: "It's not completely impossible that it still grants Bruges fishermen certain rights".
