Everyone entering an Olympic venue must have an accreditation and there are no exceptions — even if you parachute in.

The queen has one, although you won't see the purple-and-orange lanyard around her neck. One of her aides carries it for her.

French President Francois Hollande wore his when he visited and Prince William and his wife, Kate, have been seen sporting theirs at a number of events.

Official names on accreditations can be quite formal. No William or Kate, instead it is "HRH Duke of Cambridge" and "HRH Duchess of Cambridge."

Queen Elizabeth II needs no introduction — Buckingham Palace confirms hers simply reads "Head of State."
