Prince William has received another public vote of confidence from his grandmother and has been made a Personal Aide-de-Camp to The Queen.

The Duke of Cambridge's honorary appointment was detailed in the Court Circular and The Duke wore the insignia of the position for the first time at the St Patrick's Day parade for the 1st Battalion Irish Guards at Mons Barracks in Aldershot, Hampshire, where Kate got her high heels stuck in a grating and expressed a preference for a male son.

The honour goes back to Queen Victoria, who was the first to institute the appointment of a small group of personal Aides-de-Camp (ADC) positions, with one of the earliest holders being Prince Louis of Battenberg.

Charles is also a Personal Aide-de-Camp to the monarch, and the Duke of Edinburgh was made Personal Aide-de-Camp by The Queen's father, King George VI.

Principal ADC is an office held by some high-ranking officers in the Armed Services and includes carrying duties such as attendance on The Queen at the State Opening of Parliament or representing The Queen at memorial services.

Other ADCs are also chosen from the Armed Services.

Last summer, William was given the highest honour in Scotland after being installed as a Royal Knight of the Order of the Thistle at a service in Edinburgh.
