How many pen- pushers, equerries
and lickers of the royal stamps were involved, one wonders, in this arcane method of communication?
Both Prince Charles and Prince Andrew have had women equerries.
Major Liz Towell and Major Joyce Gillison were both seconded from the Royal Irish Regiment as Prince Andrew's temporary equerries.
Most equerries to the Royal Family are appointed from the Army, Navy or RAF, with each service taking turns to put forward an aide for two-year tours of duty.
Sarah's first husband Major Hugh Lindsay, one of the Queen's favourite Equerries
, was swept to his death at Klosters, Switzerland, in the avalanche that nearly killed Charles in 1988.
