Spice Girl-turned-fashion designer Victoria Beckham has topped a business magazine's list of Britain's 100 foremost entrepreneurs.

Mother-of-four Beckham, who shot to fame as Posh Spice before marrying David Beckham, beat heavyweights such as Sir James Dyson to lead a list compiled by Management Today (MT).

The 40-year-old's first fashion boutique in London's Mayfair opened in September and her Victoria Beckham brand has seen revenue grow by 2,900% in five years from a turnover of £1 million to £30million this year, the magazine said.

Philip Beresford, the man behind the Sunday Times Rich List, wrote in MT: "It's her finely tuned business acumen that wins her the top spot."

Two other fashion retailers made it into the top 10 - Mahmud Kamani, of Boohoo.com, was third, and Julian Dukerton, of Supergroup, home of the Superdry brand, fourth.
