Last month, a man was detained by police after eggs were thrown at Charles and Camilla, his wife and the Queen consort during their engagement in northern England.
The latest development comes as the royal family braces itself on Thursday for the release of a Netflix documentary series about the king’s youngest son, Prince Harry, and his wife, Meghan, and their latest expected criticism of the royal household.
It also comes a week after the royals became involved in a new race row involving Prince William, the godmother of Charles’ eldest son, who made “unacceptable” comments about race and nationality to a guest at a Buckingham Palace ceremony. He had left his honorary role after making the remarks.
Egg protests are nothing new to royals: eggs were thrown at Elizabeth’s royal car in 2002 while she was visiting Nottingham, central England, and anti-British protesters threw stones at Charles during a walk in central Dublin in 1995. Eggs were thrown.
