Specifically, the Duke of Sussex will join his brother, the Prince of Wales, in uniform around the coffin at Westminster Hall ahead of the Queen’s funeral on Monday. Harry, who saw action on the front line during two tours in Afghanistan, has not previously had the chance to don his military uniform as he publicly mourns the fact that he is no longer a working royal. However, royal sources say the king has decided his youngest son will wear uniform for the vigil, saying he will stand at the foot of the coffin, with William at the head. Despite being a former army officer, he wore civilian dress for official events, including walking behind his grandmother’s coffin on Wednesday when it was taken to Westminster Hall to lie in state.
