Exports of food and drink from the UK to the grand duchy were 91.1% lower in January this year than last January, the last month of the UK’s membership of the EU. This decline was the largest in the EU, where the average drop in the value of exports was 75.5%.

A report from the UK Food and Drink Federation also showed that from £0.9m (€1.04m) of British meat, tea, beer, cheese, cereals, biscuits, whisky and the like being shipped last January, goods worth just £0.1m (€0.12m) made it through the new, tougher border arrangements this year.

Conversely, Luxembourg exports to the UK jumped 86.7% to £0.2m (€0.25m), helped by the fact that the British authorities have yet to implement checks on goods going into the UK.

Care should be taken with these figures, as it is possible that these numbers are skewed by pre-Christmas stockpiling. But the direction of travel is clear enough: fried breakfasts, strong cups of tea, and your favourite warm beer will be harder to come by in the grand duchy.
