Jubilee celebrations are culminating in a four-day UK bank holiday weekend, which lasts from Thursday to Sunday.
Official jubilee celebrations began in January when Fortnum & Mason launched the platinum pudding competition to find a dish to dedicate to the queen's 70 years on the throne. The winning recipe was created Jemma Melvin with her lemon Swiss roll topped with an amaretti trifle.
The Sandringham and Balmoral estates will be open for visitors to enjoy the celebrations across the long weekend.
Performers, dancers, musicians, military personnel, key workers and volunteers will tell the story of the queen's reign in the platinum jubilee pageant, which will see a River Of Hope — made up of 200 silk flags — make its way along The Mall, outside Buckingham Palace.
It is not clear which events the queen will attend as she was ordered to rest by doctors in October last year after an overnight stay in hospital for unspecified preliminary investigations.
The bulk of the jubilee duties are likely to be divided among the rest of Britain's royal family, including the Prince of Wales and Duchess of Cornwall.
Here are all of the events taking place over the jubilee bank holiday weekend:
Bank holiday, June 2: Queen’s Birthday Parade (Trooping the Colour)
A display of horsemanship and military precision on Horse Guards Parade by the 1st Battalion, Irish Guards and more than 1,200 officers and soldiers from the Household Division.
