Kate Middleton had poignant reason to wear brooch at Trooping the Colour

The sweet meaning behind Kate Middleton's brooch at the Trooping the Colour has been revealed. The Princess of Wales, who is battling cancer, appeared at the Royal Family event on Saturday June 15, with her children alongside her.

The mum-of-three, who announced her cancer diagnosis back in March, wore a Jenny Packham dress, along with Philip Treacy hat. The dress featured an Irish Guards Regimental Brooch due to Kate being a Colonel of the Irish Guards.

Discussing her return on GB News, commentator and historian Rafe Heydel-Mankoo said King Charles is "delighted" that the Princess of Wales is able to attend the event, as she is the "strength and stay and future of the monarchy".

Heydel-Mankoo said: "The King is delighted that the Princess of Wales is there. He knows that she is the strength and stay and the future of the monarchy, and she has done so much to rise above everything else that's been happening on and provide that symbol of constancy and stability."

Heydel-Mankoo told GB News: "Kate is much like her mother-in-law, and indeed the Queen Mother as well. The power behind the throne as King George VI knew was the Queen Mother. And I think to a great degree, Her Royal Highness the Princess of Wales will prove to be that vitally important strength for Prince William in the years ahead and when he eventually becomes King."

Kate said on Friday: "I'm looking forward to attending The King's Birthday Parade this weekend with my family and hope to join a few public engagements over the summer, but equally knowing I am not out of the woods yet.

"My treatment is ongoing and will be for a few more months. On the days I feel well enough, it is a joy to engage with school life, spend personal time on the things that give me energy and positivity, as well as starting to do a little work from home.

"I am learning how to be patient, especially with uncertainty. Taking each day as it comes, listening to my body, and allowing myself to take this much needed time to heal. Thank you so much for your continued understanding, and to all of you who have so bravely shared your stories with me."
