The Queen will be the guest of honour at a huge street party organised just for her on Sunday as three days of celebrations to mark her 90th are brought to a spectacular close.
Joined by her husband Prince Philip, and grandsons the Duke of Cambridge and Prince Harry, the monarch will head down to The Mall where she will celebrate the milestone event with 10,000 guests as they enjoy the open-air party and Patron's Lunch.
The finale birthday event will see guests, who paid £150 to attend and are mostly from charities that have the Queen as patron, enjoy a quintessentially English day out with a lunch which includes Pimm's, mini pork pies, and cupcakes served in hampers.
After lunch there will also be a parade with volunteers from Patron's organisations bringing to life the decades of the Queen's reign as they put on a carnival-inspired procession.
Event organiser, and grandson to the Queen, Peter Phillips said the street party was a way to honour the Queen's commitment to the organisations she personally attached to and to "give something back to them".
He said: "She thought it was a fantastic idea to be able to bring all these organisations together in one go.
"She was delighted that on this occasion she was able to give something back to all of these organisations and give them a platform to be able to celebrate their association (with her)."
The party brings to a close three days of celebrations to mark the monarch's birthday which included a service at St Paul's cathedral on Friday and the Trooping the Colour on Saturday.
