Queen Elizabeth II stepped gingerly onto the Buckingham Palace balcony Thursday, drawing wild cheers from the tens of thousands who came to join her at the start of four days of celebrations of her 70 years on the throne.

LONDON, June 2: Tens of thousands of royal supporters lined the streets of London on Thursday to celebrate Queen Elizabeth's Platinum Jubilee and kick off four days of pomp, parties and parades to mark her record-breaking 70 years on the British throne.

Queen Elizabeth thanked all those involved in her Platinum Jubilee celebrations ahead of four days of pomp, parties, parades and public holidays to herald her record-breaking 70 years on the British throne.

When Ajay Chhabra was asked to design a pageant performance to celebrate Queen Elizabeth II’s Platinum Jubilee, he knew what would make the perfect centerpiece: cake. Not just any cake, but Elizabeth and Prince Philip’s 1947 wedding cake. The four-tier, nine-foot (2.7-meter) confection was dubbed “the 10,000-mile cake” at the time because it was whipped up with sugar, dried fruit, rum and brandy from all corners of the Commonwealth, from South Africa to the Caribbean to Australia and the South Pacific.
