The climactic day of the Platinum Jubilee will be marked by a pageant celebrating some key aspects of British life.
It will be split into four acts: For Queen and Country, The Time Of Our Lives, Let's Celebrate, and Happy and Glorious. The first act will be a military parade containing 1,750 people and 200 horses from the Army, Nacy, RAF and Commonwealth - making it one of the biggest parades in British history.
Meanwhile, the second act will show representations of British life "since 1972" and will show off aspects of British culture, music and technology. Following this will be the third act which aims to tell the story of the Queen's life in 12 chapters and will feature a 20ft puppet of a princess accompanied by a pack of cor and 80 dancers mimicking the white coronation robes.
