Princes William and Harry will stand vigil together by the queen's coffin, both in their military uniforms

London — Queen Elizabeth II's eight grandchildren will stand vigil by her coffin in London's Westminster Hall on Saturday evening, Kensington Palace announced Friday. At the request of King Charles III, both William, Prince of Wales, and his brother Harry, Duke of Sussex, will wear military uniforms.

The move comes after the king gave previous guidance, reported by CBS News contributor Royah Nikkhah, that only working members of the royal family would be permitted to wear their uniforms during ceremonial events leading up to the queen's state funeral.
