Pub opening hours will be extended on June 10 and 11 to mark the Queen's 90th birthday, David Cameron has announced.
The milestone will be marked with a weekend of national celebrations to coincide with her official birthday along with other events to mark the day she was born, April 21, 1926.
During Prime Minister's Questions, Mr Cameron told MPs: "We will be extending pub opening hours on the 10th and 11th of June to mark Her Majesty the Queen's 90th birthday."
A service of thanksgiving, attended by the Queen and Duke of Edinburgh, will be held at St Paul's Cathedral on Friday June 10.
The following day the traditional Trooping the Colour ceremony, also known as the Queen's Birthday Parade, will be staged in Horse Guards Parade and on the Sunday the Patron's Lunch will be held in The Mall.
Two graces, sometimes referred to as informal prayers, have also been published for use as thanksgivings at the start of other celebrations such as street parties.
