Kensington Palace has told Sky News it will not be commenting on Prince William's decision not to attend the final, which would have marked his first visit to Australia, a Commonwealth realm, since 2014.

It's understood the family will be watching the match from Norfolk.

Sky News has contacted the FA for comment in relation to Prince William's decision not to attend.

He visited St George's Park, the squad's home training base, before they left for the tournament.

Decision 'calls William's support into question'

Mandu Reid, leader of the Women's Equality Party, is among those who has criticised William's decision.

"Women have fought for decades to get even an iota of recognition in football," she wrote on X, formerly Twitter.

"For Prince William to shirk the World Cup final is the wrong move, deeply disappointing and calls into question how sincere he is when he proclaims his support for women's sport."

Queen Letizia of Spain is set to travel to Australia for the final, but no British royal will be present.

Prime Minister Rishi Sunak is also not expected to attend. The British government will instead be represented at Sunday's match by Foreign Secretary James Cleverly and Culture Secretary Lucy Frazer.

Sir Keir Starmer, leader of the Labour Party, tweeted ahead of the match: "Seeing how the @Lionesses inspired my daughter last year was an incredibly special moment for me.

"Whatever the result tomorrow, this England team has already left its mark."

Lionesses manager Sarina Wiegman has said England's players are hoping to play their "best game ever", with the team feeling buoyed by the "incredible" support they have received.

England hope to end World Cup trophy drought

The England boss was speaking at a news conference alongside captain Millie Bright, who said the fact the players have a good relationship with their manager off the pitch helps with their performance in matches.

The England women's team have the opportunity to lift the game's most coveted prize for the first time.

It will also end a near-60-year wait for England to experience World Cup glory - with the men's team not having won since 1966.
