Journalist Gordon Rayner said the Duke of Cambridge had planned to spend the second half of his 30s working with the Duke and Duchess of Sussex as part of the “Fab Four”. But Mr Rayner cited friends as saying that Harry and Meghan quitting royal duties for a new life in the US meant William had to “start from scratch”.

The Telegraph’s associate editor said: “William has been as much a victim of events as of circumstance: he did settle on a plan to spend the second half of his 30s tackling the world’s ills using the star power of the Cambridge/Sussex ‘Fab Four’, only for Harry and Meghan to walk away.

“Friends say Megxit left him having to ‘start from scratch’, with Covid further hampering his attempts to define his public role.”
Mr Rayner’s comments come ahead of the future King’s milestone 40th birthday next week.
