Nothing stirs Anglo-Gallic passions quite like the sight of gunboats in the Channel. The presence of several hundred patrol boats in the waters around Jersey – one of the picturesque Channel islands that provides offshore banking to the mega-rich – is the latest act in the Brexit farce. Jersey is one of the most patriotic and most pro-Brexit places you will find. Although, adding to the irony, it isn’t even part of the UK. Unfortunately, this foolish bravado in a spat over fishing rights is a sign of things to come. Until 2026, the UK is transitioning away from the Common Fisheries Policy. After that, an annual agreement with the EU on fishing quotas will need to be negotiated. That looks like wishful thinking.
