Ed Sheeran is to perform his love song Perfect at the Jubilee Pageant in a special tribute to the Queen of England and her late husband, the Duke of Edinburgh.
At the finale of the carnival procession through the streets of London on Sunday, ahead of the UK's national anthem, the star will sing the hit romantic ballad as footage featuring images of the Queen and Philip fills the giant screens around the stage.
Philip - the man the Queen described as her "strength and stay" - was married to the monarch for 73 years and devoted decades of his life to royal duty.

He died at the age of 99 in April last year during the pandemic, leaving the Queen grieving for her lifelong confidant.
Other tributes to Philip will appear in the pageant, with a Bollywood-inspired interpretation of the Queen and the duke's wedding day.
A 20ft (6m) wedding cake, housing a sound system playing classic Bollywood anthems and accompanied by 250 Bollywood dancers, will process down The Mall in a reimagining of their 1947 marriage celebration.
A representation of Philip’s beloved sailing boat Bluebottle will feature in the section devoted to the "Queen’s Favourites", which will also include puppet corgis and horses.
