The Prince of Wales was subjected to chants of “Lizzie’s in a box” and “If you hate the royal family, clap your hands” by Celtic fans during Aston Villa’s Champions League clash with the Scottish club.
Away supporters also displayed a banner in the stands glorifying an intruder who found his way into Queen Elizabeth II’s Buckingham Palace bedroom, days after Prince William was born.
The Prince of Wales, Villa’s most famous fan, attended the match on Wednesday night local time and was seen celebrating wildly as Villa raced to a 2-0 lead.
Home supporters were heard singing the national anthem in response to the abuse by Celtic fans, who were also said to have sung about the Prince’s brother, the Duke of Sussex.
The visitors are certain to face punishment from Uefa, the European football union, after their fans let off a green flare when their side pulled a goal back.
