I've just heard about the passing of Her Majesty The Queen Elizabeth, and I must say that, although I'm not British, I was definitely shocked after seeing that. My condolences to all of Britain for this sad news!
As a British subject, although I'm far from being a royalist, and having had my ups and downs with this country, I am deeply saddened by the passing of our beloved Queen. She is the most influential person in the world I believe, and today will be marked in history.
antenn I'd support a "NationalDayofMourning" hashtag. (We already used in 2017, for a bus crash killing 17 Hungarians) Black cars can be also included.
The day of her funeral which is likely going to technically be such day in the UK?
