London 2012 Olympics: The torch begins its journey across London Its journey will culminate at the Olympic Stadium on Friday evening where it will be passed from athlete to athlete before being used to light the cauldron, signalling the official start of the London 2012 Games. The identity of the final torch bearer, whose job it will to light the cauldron during the opening ceremony, is being kept a closely guarded secret but several possible candidates have already been suggested. These include Sir Steve Redgrave, the five-time Olympic gold medallist, and Daley Thompson, the decathlete, who won gold at 1980 and 1984 Olympic Games. On Friday, the torch relay - which started at Land's End, in Cornwall, on May 19 - made its way through Kent. Its journey was briefly delayed when a teenager broke away from the crowd and attempted to grab the torch from Anna Skora, 23, from Lubli, in Poland, as she carried it through Gravesend, but he was quickly restrained by the police escort. A 17-year-old, from Gravesend, was later arrested by police. People began gathered from early morning to watch Miss Sinha carry the torch from the Royal Observatory in Greenwich Park, down a steep hill to the London 2012 equestrian arena. Miss Sinha is a talented swimmer, who won a silver medal in the 100m butterfly when she was just 12 years old and has qualified two years in a row for the British Championships. At the arena, she passed the flame onto Ella Statham, also 15, who was nominated for her volunteering work with the London Football Association. Later, Sir Robin Knox-Johnson, the first person to sail solo non-stop around the world and the founder of the Clipper Round the World Yacht Race, carried the torch around the recently restored Cutty Sark. The torch will pass through every London borough this week, with Daley Thompson and Doreen Lawrence, the mother of the murdered teenager Stephen Lawrence, among the torchbearers. The torch's route today: Greenwich Dozens of people lined the streets of the Royal Borough of Greenwich from early this morning to watch the Olympic torch begin its journey through London. They started arriving as early as 5am but were not be able to see the start of today's relay as Greenwich Park, home of the Royal Observatory - where the first torchbearer set off from, was closed to the public. Once the torch left the park it crossed Romney Road - where a small crowd gathered - and passed through the old Royal Naval college, before making its way to the Cutty Sark, where dozens more people were waiting with flags. Before setting off Miss Sinha held the torch aloft for photographers outside the Royal Observatory
