A British trawler was seized by France and another fined, in fishing rights arguments. The French checks on UK trawlers overnight are not part of the range of retaliatory actions announced in the post-Brexit row. But there is no doubt it is a message of what is to come. From 2 November British and Channel Islands fishing boats will not be allowed to offload fish at French ports. There will be intensified controls at Calais and other entry points for UK trade by ferry and tunnel. The French authorities will conduct a ‘grève de zèle’ (punctiliously looking for violations) on fish and other imports which will create long tail-backs to remind British subjects of the costs of go-it-alone. The UK government said the threat of sanctions was ‘not what we would expect from a close ally and partner’. The boat owner said his fishing activity for scallops was ‘entirely legal’.
