Vigil of the Princes The Queen's four children stand at her side in Westminster Hall

The Vigil of the Princes refers to occasions when members of the British royal family have "stood guard" during the lying in state of one of their relatives during or as part of a British state or ceremonial funeral. This occurred for King George V in 1936, Queen Elizabeth The Queen Mother in 2002, and three times for Queen Elizabeth II in 2022. During the first two of these occasions, only male members of the British royal family joined the vigil. In 2022 however, the Princess Royal took part alongside her three brothers in vigils for her mother, Queen Elizabeth II.
