In a statement, it said: "Buckingham Palace is pleased to confirm that The Duke of Sussex will attend the Coronation Service at Westminster Abbey on 6th May.

"The Duchess of Sussex will remain in California with Prince Archie and Princess Lilibet."

Harry, who revealed his troubled relationship with the royal family in his controversial Netflix documentary and autobiography Spare, will be there to witness Charles and his stepmother the Queen Consort be crowned in Westminster Abbey on 6 May.

The news ends months of speculation about whether the couple would show up to the King's big day, but will undoubtedly see Meghan accused of snubbing the monarch and the royal family.

The date of the coronation is also Archie's fourth birthday.

In Harry's controversial ghost-written memoir, he admitted to regular drug-taking and laid bare his frustrations with his family.

He claimed his brother William, now the Prince of Wales, had knocked him to the floor after calling the Duchess of Sussex "difficult", "rude" and "abrasive".

The duke claimed his father, now the King, put his own interests above Harry's and was jealous of Meghan and Kate, and that the Queen Consort sacrificed him on "her personal PR altar".
