King Frederik celebrates Denmark’s equaliser against England as Prince William watches on

Prince William has also been watching the game and was seen belting the national anthem at the start.

The pair stood together as they both supported their respective teams at the England vs Denmark match at the 2024 Euros.

Prince William's appearance at the Frankfurt Arena in Germany on Thursday comes the day before his 42nd birthday.

He has travelled to the event on his own as his wife Princess Kate recovers from her cancer diagnosis.

King Fredrik attended the game with his daughter Princess Josephine.

The match has fallen on a school night for Prince George, 10, Princess Charlotte, nine, and Prince Louis, six so the Prince of Wales has flown solo.

William, president of the Football Association, faced criticism last year for not attending the Women's World Cup final in Australia when the Lionesses lost to Spain.

It was the first time the Lionesses had reached the final of a World Cup, and the first time an England football team had competed in a World Cup final since the men's side beat West Germany in 1966.

William reportedly harboured concerns over the length of the journey, with the game being played in Sydney, Australia.

At the time, the royal was forced to issue an apology to the Lionesses following the public outrage.

Speaking alongside Princess Charlotte in adorable footage, the Prince of Wales said: "We’re sorry we couldn’t be there in person.

"We’re so proud of everything you’ve achieved and the millions you’ve inspired here and around the world."

Spanish royalty was present at the final, with Queen Letizia travelling to Australia.

She was accompanied by her daughter Infanta Sofia, 17, to show the country’s "commitment" to national football.
