Revellers attending The Mall street party during the Queen's 90th birthday weekend celebrations will be charged £150 a ticket.
The Queen's grandson Peter Phillips has announced the ticket price and further details about the Patron's Lunch, a not-for-profit event, he is helping to organise.
- The Patron's Lunch will be the culmination of a weekend of national events this summer marking the Queen's official 90th birthday.
- The event will honour the Queen's lifetime dedication to service and mark her patronage of more than 600 charities and organisations.
Speaking to our main presenter Pam Royle, Mr Phillips said it would have a "carnival atmosphere" with around 10,000 guests - the vast majority representatives from the Queen's patronages.
In February a ballot will open to the public for a minimum of 1,000 tickets, with winners able to buy them from the event's website.

Attendees will be enjoying hampers of food at tables set up in the famous London thoroughfare on June 12th.
A carnival parade will travel along the Mall entertaining the guests and the Queen and Duke of Edinburgh will take to a stage to listen to speeches marking the occasion, before sitting in a royal box with the Duke of Cambridge and Prince Harry, joint presidents of the event, for part of the day.
Mr Phillips is helping to organise the event in his role as director of Sports and Entertainment Ltd (SEL), a global events agency which came up with the idea for The Mall street party.
Mr Phillips said the Queen heard about his plans to organise a street party during her 90th birthday weekend celebrations before he had a chance to tell her.
The Queen is known for her sharp sense of humour and her grandson said when he first approached her to tell her the idea - after formally pitching it to Buckingham Palace - she said: "I've heard you're up to something."
Mr Phillips said: "It's a huge honour that I was allowed to do it."
He added that his grandmother was fully supportive of his efforts: "Secondly there's a huge amount of pride, the fact that I'm able to celebrate, to put something on, to put a celebration on which ultimately she appreciates, she enjoys and she thinks is a great idea."
- 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 street party.
- During the day the carnival parade will make two laps of a circuit around St James's Park that includes the Mall.
The majority of the tickets have been allocated to the hundreds of organisations and charities associated with the Queen and they will be allowed to raise money with 40% of their tickets.
The organisers also hope communities around the country will be inspired to stage Patron's Lunches in their own areas and raise money for local projects.
Any surplus from the not-for-profit event will be allocated to a newly created Patron's Fund, which will be used to support specific initiatives and projects run by the Queen's charities.
