Gun salute for Queen Elizabeth II, who turns 91World | Apr 21, 19:32
A troop of the Royal Horse Artillery will ride horse-and-gun carriages past Buckingham Palace before staging a 41-gun salute in Hyde Park at noon local time. There will also be a 62-gun salute at the Tower of London an hour later.
The queen is Britain's oldest and longest-reigning monarch, having become queen on February 8, 1952. She is also the world's longest-reigning living monarch since the death of Thailand's King Bhumibol Adulyadej last year.
The queen usually spends her birthday privately. She also has an official birthday, marked in June _ when the weather is better _ with the "Trooping the Color'' military parade.-AP
