Royal aides were ‘cringing’ last night after the Duchess of Sussex posted a ‘behind the scenes’ video from her Vogue magazine editorship showing her putting on a silly hat and playing with a party blower.

Meghan and Harry uploaded the clip to their Sussex Royal Instagram feed to celebrate the fact that the Forces For Change edition in August was the best-selling of the decade.

But the move was last night being seen as another salvo in the battle between the couple and Buckingham Palace, following their decision to step down from royal duties and move abroad.

The Mail understands that Meghan and British Vogue editor Edward Enninful had tried to put the video out several times since last summer but had been blocked by palace officials because it was seen to be too ‘inane’ and frivolous.

They feared the image of Meghan wearing a party hat with a blower in her mouth could come back to haunt her, and could even be made into a ‘Megxit meme’, a humorous viral picture.
