King Charles has ordered royals to wear black armbands in remembrance of those killed in the Air India plane crash for Trooping the Colour on Saturday.

The monarch has requested a minute's silence in tribute to the 241 passengers and crew killed when a Boeing 787 Dreamliner bound for Gatwick Airport came down on Thursday in the Indian city of Ahmedabad.

Black armbands will be worn by the head of state and senior royals riding in the ceremony to mark the King's official birthday.

On horseback and wearing the armbands will be the Prince of Wales, Colonel of the Welsh Guards, the Princess Royal, Colonel Blues and Royals, and the Duke of Edinburgh, Colonel Scots Guards.

A Buckingham Palace spokesperson said Charles requested amendments to the Trooping the Colour programme 'as a mark of respect for the lives lost, the families in mourning and all the communities affected by this awful tragedy'.
