Ministers are under pressure to allow shops to sell meat, fruit and vegetables in pounds and ounces ahead of Britain leaving the European Union.

Customers have been asking shop owners if they can have groceries weighed in pounds and ounces rather than grams and kilograms ahead of Brexit.

The British Weights and Measures Association said that “one or two” shops had been in contact every week since the June 23 referendum asking if they can sell produce in imperial measurements.

It said that this figure was likely “the tip of a much bigger iceberg”.
