Some years ago I opined that London was not really an English city any more— John Cleese (@JohnCleese) May 29, 2019
Since then, virtually all my friends from abroad have confirmed my observation
So there must be some truth in it...
I note also that London was the UK city that voted most strongly to remain in the EU
Cleese has been clarifying his tweet and telling us that he has many "foreign friends". Sad!
