Thousands brave rain for queen's 90th birthday picnic

Thousands of people gathered in the rain for a street party outside Buckingham Palace on Sunday, part of a weekend of celebrations to mark Queen Elizabeth II's 90th birthday.

With The Mall lined with Union flags, picnickers donned plastic ponchos as a summer shower hit central London. 

But guests insisted that the downpour would not put a dampener on the event.

"Rain won't spoil the party," said picnicker Noreen Chisholm. "Everybody is so happy to stand in the rain to be part of the queen's birthday."

"The British spirit will come through the rain," added fellow guest Andy Moor.

Around 10,000 people attended the Patron's Lunch on The Mall where the queen gave a short speech thanking them for their birthday wishes and joked about the length of the festivities, which have spanned several months.

A smiling queen, dressed in fuchsia, and her husband Prince Philip emerged from Buckingham Palace after the rain had stopped in a chauffeur-driven, open-topped 4x4 to wave at crowds who lined The Mall to see her.

Briefly addressing the crowds to thank them for their good wishes, she added: "How I will feel if people are still singing 'Happy Birthday' in December remains to be seen."

Tickets for the event cost £150 (190 euros, $215) with most of the guests from over 600 organisations with which the queen has links.

Guests dined on hampers containing sandwiches, snacks and puddings from British producers, while adults even got a can of Pimm's, a fruit punch popular at summer garden parties in Britain.

The queen's grandson and future king Prince William paid tribute to the monarch's "sharp wit" and "strong health".

"The queen at 90 is the only head of state that world leaders can turn to for a first hand perspective on the arc of history over the last six decades," he said.
