10,000 people braved the weather to take part in a picnic hamper lunch to celebrate the Queen's birthday later today, in the final event of the official celebrations.
Ten thousand people sat down at the rows of tables on The Mall for a picnic hamper lunch, with Buckingham Palace in the backdrop, before the Queen, the Duke of Edinburgh, the Duke of Cambridge and Prince Harry arrived to watch a carnival-style procession.
Prince William has paid tribute to the Queen in an address to crowds at The Mall.
The Duke of Cambridge said the Royal Family has had plenty of reasons to celebrate since the Queen turned 90 in April, including her "strong health and relentless energy, her sharp wit and famous sense of humour".
He also paid tribute to the Queen's patronage of over 600 charities.
Most of the 10,000 tickets were allocated to the 600 charities and organisations of which the Queen is a patron, who were forced to pay £150 per head for the honour, prompting heavy criticism. An unnamed benefactor eventually stepped in to buy under 10% of the tickets on behalf of the charities.
The event was organised by the Queen's eldest grandson Peter Phillips, director of Sports and Entertainment Ltd (SEL), who will receive and undisclosed fee for staging. 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".
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.
