The Princess of Wales made a surprise joint appearance with Prince William at Everton's Hill Dickinson Stadium in Liverpool to launch a new suicide prevention "toolkit", marking their first shared royal engagement since the summer break and since the Duke and Duchess of Sussex returned to the UK. William had originally been due to host the event alone, and the couple were joined by high-profile figures from sport and broadcasting, underlining the profile the Royal Foundation is giving to mental health and suicide prevention initiatives.

The "On Your Side" toolkit, developed with the British Standards Institution and the charity Chasing the Stigma, aims to help people recognise warning signs and build confidence to offer timely support, and was launched with backing from figures including Gabby Logan, Dame Kelly Holmes, Harry Kane, George Russell, Alan Shearer, and Sir Jason and Dame Laura Kenny. The event came against the backdrop of a row over a letter from the King confirming Harry and Meghan are not working royals and that their HRH titles remain suspended, which the Sussexes say they were not consulted on, while Palace sources maintain the letter aligns with the couple's own wish to be treated as private citizens.
