On the day she turned 21, the then Princess Elizabeth pledged to dedicated her life to serving the Commonwealth, in what has become one of the best-known and most moving public declarations of her long reign.

Surrounded by her family, at the close of a week that has cemented her Commonwealth legacy for a new generation, the Queen celebrated her 92nd birthday in some style, with a Royal Albert Hall concert designed to honour all she has done for her country.

With a line-up of music from each decade of her reign, the concert marked not just, as Her Majesty put it, “another birthday”, but the culmination of a lively week which brought all corners of the Commonwealth to London.

Introducing the evening the Prince of Wales led the birthday wishes with a touching written tribute to his mother.

“While all birthdays are special, this year, the Queen’s birthday falls at the end of the week-long Commonwealth Summit in London, which has brought together 53 countries.
