A schoolboy has become the youngest British mountaineer to climb Mount Everest - at the age of just 16. George Atkinson, who turns 17 on Sunday, reached the 8,848m summit - making him the youngest ever Briton to stand on top of the world. It comes less than a week after Irish man John Delaney collapsed and died 50 metres before the top, not knowing his wife had just given birth to a baby girl back home. Georges extraordinary feat saw him smash Rob Gauntletts previous record by three years. He also became the youngest climber ever to have scaled the tallest peaks of each continent. His proud mother Penny, 45, said: 'George wasnt able to phone from the summit so we havent spoken to him yet but I bet hes really pleased with himself. 'Its been a nerve-racking experience for us and the entire family has been up all night waiting for news - including his grandmother, she said. By climbing Everest, George also became the youngest mountaineer to complete the Seven Summits - the highest mountain on each continent. DM
