Hundreds of well-wishers crammed into the north London district of Camden as the Olympic torch set off on a celebratory tour of London's prime tourist sites.
Thursday was Day 69, the second-last day of the torch's 8,000-mile (12,900-kilometer) journey.
Runners are carrying the flame past famous landmarks, including the Houses of Parliament, St. Paul's Cathedral, 10 Downing St. and Buckingham Palace, where it will be greeted by Prince William and his wife Kate, Duchess of Cambridge.
It will be carried to the palace by Jon Sayer, a Scout volunteer who last year saved a man from a swollen river. Other torchbearers include comedian David Walliams, actress Joanna Lumley and Bollywood star Amitabh Bachchan.
The relay ends Friday when the last torchbearer lights the cauldron at the London Olympics opening ceremony.
