In his ceremonial role, The Marquess, whose name is David Cholmondeley, had charge over the Palace of Westminster and he also had a major part to play in grand royal events, such as coronations, having the right to dress the monarch on coronation day and to serve the monarch water before and after the coronation banquet, and also being involved in investing the monarch with the insignia of rule.

He will also play an important part in the Coronation, which many believe will take place next year.
In the past, David, 61, and his wife Rose, have been pictured with William and Kate on several occasions, including accompanying them to church.

Rose, 38, and David, tied the knot following a short engagement in 2009. The couple live at Palladian Houghton Hall in Norfolk, just over three miles away from Kate and William's Anmer Hall.
They have three children together: Alexander (the Earl of Rocksavage), Oliver (Lord Cholmondeley) and Lady Iris.
