Buckingham Palace announced the King's takeover of the honorary military role from his son the day after details of the Duke of Sussex's tell-all autobiography were released.

There had been speculation about which member of the Royal Family would be given the role, with the Princess Royal tipped for the position.

The duke was stripped of his military titles, which also included Commodore-in-Chief of Ships and Diving, and Honorary Air Commandant of RAF Honington, in February 2021 after he and the Duchess of Sussex announced their plans to stop being working royals the previous year.

In a statement to mark the 358th anniversary of the Corps of Royal Marines, the King said he was "exceptionally proud" to become its ceremonial head.

"It is the greatest possible pleasure to assume the role of your Captain General," he said.

"I am exceptionally proud to follow in the footsteps of so many members of my family over the last three-and-a-half centuries, all of whom held the role with a deep sense of admiration.

"The Royal Marines have a distinguished and unparalleled history, both on land and at sea. I draw immense inspiration from your courage, determination, self-discipline and a remarkable capacity to endure in the most extreme environments.

"I feel greatly honoured to become part of the Corps Family and very much look forward to meeting many of you in the near future. In the meantime, this comes with my heartfelt and special wishes for a very happy 358th birthday. Per Mare, Per Terram."

Day after Harry memoir announced

On Thursday, it was revealed Prince Harry's memoir SPARE will be released on 10 January.

The title appears to be a reference to the phrase "heir and a spare" - suggesting his attitude toward his place in the Royal Family.

Billed as "his story at last", the book also delves into Prince Harry's "personal journey from trauma to healing".

"With its raw, unflinching honesty, SPARE is a landmark publication full of insight, revelation, self-examination, and hard-won wisdom about the eternal power of love over grief," a description of the book reads.

Buckingham Palace has not commented on the announcement.
