The 10-year-old attended the Women’s Euros final alongside her dad, Prince William, last night (27 July)

Princess Charlotte has just very quietly achieved a major royal milestone, and it’s gone largely unnoticed.

The 10-year-old royal, who is the second-eldest of Prince William and Kate Middleton’s three children, attended the Women’s Euros final alongside her dad in Bazel, Switzerland, yesterday (27 July).

People watched around the world as Spain started off strong scoring a goal within the first 25 minutes. While nerves were high, England soon equalised, with Alessia Russo scoring in the 57th minute.

And, after we stayed 1-1 throughout the 30 minutes of extra time, football fans from all over were glued to the TV as the two teams battled it out on penalties.

England were able to retain their Women’s Euros title after beating Spain 3-1 on penalties, with Alex Greenwood, Niamh Charles, and Chloe Kelly getting the goals in the back of the net.

And, as the Lionesses lifted their trophy, Charlotte became the first of her siblings to sign an official statement using her full name, marking a very significant moment for the future monarch in training.

The full statement, posted on Kensington Royal’s official X account, reads: “What a game! @Lionesses, you are the champions of Europe and we couldn’t be prouder of the whole team. Enjoy this moment @England.

“W & Charlotte.”

It marked the very first time that Charlotte has used her full given name in public royal communications, as never before has she contributed directly to an official statement in this way.

Not only does Charlotte using her full name as opposed to just ‘C’ acknowledge her burgeoning role as a working royal, but it also suggests that the pre-teen is starting to learn how the monarchy communicates and, namely, how a signature can signify authority and authenticity.

“Thank you for supporting them in person, W & Charlotte!! Your presence must have been very inspiring for them,” penned one royal fan on X.

A second chimed in: “‘W &Charlotte’!”

“The Lionesses are incredible – true inspirations and a well deserved win (‘& Charlotte’)” gushed a third.

Another beamed: “I was seriously holding my breath till the end but the Lionesses came through! What a treat to have Prince William and Princess Charlotte there to watch their victory!”

And a final X user added: “Congratulations to the champion Lionesses. Must be exciting for Princess Charlotte to witness it live with her dad.”
