Prince William was worried after royal guards were collapsing during the UK's recent heatwaves.
The Prince of Wales was reportedly shaken after three guards collapsed as he led the Colonel’s Review at Horse Guards Parade two weeks ago. Just one week later at the Trooping the Colour and the Order of the Garter ceremony, two more guards collapsed.
A source told The Mirror: “Prince William expressed concern and was later informed about their condition. He made it clear he is keen to see measures in place to support teams on parade.”
