It is one of the many benefits of being a sovereign nation. But I know from my postbag that there is another infliction from the decades of our EU membership that many would like to be shot of, and that was the imposition of the metric system on large parts of our life.

Consumer resistance ensured that our beer is still served in pints (though not in half-pint and pint bottles when bought in supermarkets: brewers please note), and that our signposts are still marked in miles.

But we have been forced on to the Celsius temperature scale, which is less precise than Fahrenheit; we can’t buy groceries in pounds and ounces, or petrol in gallons, or wallpaper in yards, even though these measurements are second nature to most of us.

Laws criminalising imperial measures must be repealed. Pol Roger has announced that it will once more sell champagne in Churchill’s favourite pint measure: British companies must now follow where a French one has led.
