Prince Harry's attendance at his grandfather's funeral on Saturday will visibly mark his change of status within the royal family.
Following his decision with wife Meghan Markle to step away from their roles as working royals, Harry lost his honorary military titles, including that of Captain General of the Royal Marines, and as such is likely to wear a suit rather than a military uniform.

Protocol states that retired service personnel are allowed to wear their medals – but not their uniform – at official engagements once they have left the military. Furthermore, only those wearing a military headdress can salute, meaning that Harry is also not entitled to salute at the funeral, unlike his brother and his father.

It comes after Prince Harry released a personal tribute to his late grandfather. The 36-year-old – who is currently self-isolating at Frogmore Cottage after returning to London from California for the funeral service – said in his statement: "My grandfather was a man of service, honour and great humour. He was authentically himself, with a seriously sharp wit, and could hold the attention of any room due to his charm—and also because you never knew what he might say next.

"He will be remembered as the longest reigning consort to the Monarch, a decorated serviceman, a Prince and a Duke.

"So, on that note, Grandpa, thank you for your service, your dedication to Granny, and for always being yourself. You will be sorely missed, but always remembered - by the nation and the world. Meghan, Archie, and I (as well as your future great-granddaughter) will always hold a special place for you in our hearts. The message concluded, 'Per Mare, Per Terram' - which means 'By Sea, By Land' in Latin.
