It is nice to see that some City types have managed to instill the sense of entrepreneurship among their brood. Oliver Bolton , the 25-year-old son of Fidelity's Anthony Bolton , better known as the 'quiet assassin', has launched a 'pretox' drink called Alibi, a milk thistle-based beverage to be consumed before a drinking binge.

Meanwhile, Linley Lewis , the son of Numis's veteran salesman, Jeremy Lewis , has set up Ticket to Ride, a company that takes gap year students to South Africa for a three- month stint, where they combine learning to surf and charity work.
