The Olympic flame has embarked on a 70-day tour of the UK in the run-up to the London 2012 Games. Triple Olympic gold medallist sailor Ben Ainslie was the first torchbearer in the 8,000 mile relay, which left Land's End, Cornwall, this morning. Cheering crowds greeted the flame as it passed through lanes and streets. The flame is travelling through Cornwall into Devon where it ends its first day with an evening celebration on Plymouth Hoe.
