The Duke of York wore a morning suit, while the King wore full day ceremonial uniform with the rank of Field Marshal, the Princess Royal wore Royal Navy full ceremonial uniform in the rank of Admiral and the Earl of Wessex wore the blues uniform of the Honorary Royal Colonel of the Wessex Yeomanry.
The other ceremonial events are a procession from Buckingham Palace to Westminster Hall and service of prayer and reflection on Wednesday, a vigil at Westminster Hall, the state funeral at Westminster Abbey on Monday and the following committal service at St George’s Chapel Windsor.
One exception has been made for Prince Andrew to wear uniform on a single occasion, a vigil in Westminster Hall as a “final mark of respect” for his mother. It is expected to be the full military dress uniform of a Vice Admiral of the Navy, the only military rank that he still holds.
The late Queen’s grandchildren, including Prince Harry, are no longer expected to attend such vigil.
