10,000 to join Queen for her 90th birthday charity lunch (2)

Celebration: The Queen is said to be 'really excited' about the events, which will include a carnival parade and an enormous street party

Help Musicians UK said it had paid for its ten tickets from a ‘budget set aside for that type of event’. And Lea Bennett, secretary of Island Sailing Club, said 14 members had tickets. ‘The club is not footing the bill. Individual members are paying,’ she said.

David Anderson, the chief officer of the Cleveland Bay Horse Society, revealed that members would also pay personally for the 20 tickets they had been allocated. ‘I think at the end of the day it’s what you want to spend your money on isn’t it?’ he said. ‘I don’t think it’s out of the ordinary. If I wanted to go to a show in London I would be spending that sort of money.’

Ed Aspel, executive director of fundraising and marketing at Cancer Research UK, added: ‘We hope to invite fundraisers and volunteers who have worked tirelessly for Cancer Research UK, as a way of thanking them for their time and dedication. We hope this will be a memorable occasion for them and a fantastic day for all involved.’

A spokesman for the Patron’s Lunch explained: ‘Organising an event of this magnitude in this location requires significant investment. The Patron’s Lunch is a not-for-profit event, and whilst we have the generous support from our partners, it does not cover the full cost.‘This is a truly unique event – it is a once-in-a-lifetime, never-done-before celebration. This ticket is a very special one that gives people the chance to be part of this huge street party to honour the lifetime of service of the Queen.’

The Queen turns 90 on April 21 but the weekend of official celebrations will not be held until the summer. On Friday June 10 there will be a National Service of Thanksgiving at St Paul’s Cathedral, followed by the annual Queen’s Birthday Parade on Horse Guards on the Saturday. The Patron’s Lunch will take place on Sunday June 12.

The Mall will be transformed, with a thousand tables, each seating ten people, and ten thousand chairs needing to be laid out.

Guests are being treated to a wicker hamper lunch provided by Marks & Spencer and refreshments including Pimm’s, PG Tips tea and Wall’s Ice Cream.

They will be allowed to arrive from 10am, with the Queen and Prince Philip making an entrance in their open-topped State Review Vehicle, a new hybrid-powered Range Rover, at lunch-time.There will be live ‘carnival style’ entertainment with a colourful procession of entertainers representing the Queen’s patronages travelling the length of The Mall and around the Royal Parks.

Concern: Questions are being asked about why organisations supported by the monarch should be asked to meet the cost of attending an official royal celebration of their role out of their own funds.

Unique event: However, there has been concern that charity workers for the Queen's organisations will be charged £150 each for a ticket. Pictured, the Queen meets German children while on a state visit in Berlin in June 2015

This will allow members of the public not lucky enough to secure tickets to join in. The BBC will broadcast the event and giant screens will transmit the spectacle, as well as events celebrating the Queen’s birthday around the Commonwealth.

The Queen will view events from a specially built Royal Box at the Queen Victoria Memorial.Mr Phillips said that he hoped the event would also inspire communities across the country to hold their own street parties. Yesterday the Government issued revised street party guidance to make it easier to hold local events. Buckingham Palace said: ‘Her Majesty is looking forward to attending and seeing representatives of her many patronages which do outstanding work across a range of fields.’

A source added: ‘Planning and ticketing details are a matter for the event organisers.’
