Virgin media founder Sir Richard Branson, 64, was a dyslexic schoolboy from Buckinghamshire until he started his own business aged 16. He began selling records through his magazine ironically called The Student raking in sales by undercutting high street store prices.

A young Mr Branson was told by his headmaster that he would either end up in prison, or become a millionaire his teacher fell short of the mark, as the music magnate is now worth £2.7bn. Sir Richard launched Virgin Records in 1972 aged just 21 from a country estate in Oxfordshire. The company's first release Mike Oldfield's Tubular Bells (1973) instantly topped the charts.
