Cameron, 39, quit his degree course with six months to go, much against his mother’s will. It proved a shrewd move. He co-founded Chester-based Moneysupermarket.com, a financial services website, in 1999 with Simon Nixon (qv). It floated on the stock market in July 2007, when it was worth £843m. Cameron, who retained a stake, had quit working there some years earlier. Nixon paid him £162m for most of his holding in the run-up to the float. Cameron sold the rest for £38m and is worth £132m.
