If they are that weak then Britain is better off without them. I can remember when Brits were some of the finest, toughest people on the planet. It’s good that these people are identifying themselves. There should be no such thing as duel citizenship.
When the US required people or give up their citizenship in other countries before they became a citizen of the auS we had people who were actually proud to be American , not just better off financially.
When was it when you remember them to be the toughest people on the planet? World war two?
