No, not in the UK. A story in the Mirror online today.
The Danish Royal Family has announced that four grandchildren of Queen Margrethe will lose their prince and princess titles from January 1, 2023 - and says it is in line with "other royal houses". The move affects the children of the Queen's second son Prince Joachim - Prince Nikolai, 23, Prince Felix, 20, Prince Henrik, 13, and 10-year-old Princess Athena. Instead, they will use titles of count or countess and be referred to as their excellencies from next year.
I love the photo that accompanies the piece, they look such a happy family, smartly but not extravagantly dressed and not a uniform or medal in sight.
