The City of York has produced some of the region's wealthiest working tycoons, a new survey has revealed.

The list, which has been compiled by Yorkshire Business Insider magazine, reveals a number of the region's richest people have a York connection.

Britain's answer to Bill Gates, 46-year-old Peter Wilkinson, who is the 4th richest in Yorkshire with a fortune of £430 million, was educated in York, the analysis reveals.

The success of his computer and internet firm Systime has been behind a large chunk of his millions.

Mr Wilkinson's company was behind the setting up of Sports Internet, which was sold to BSkyB netting him around £127m worth of BSkyB shares.

Meanwhile Terry Sadler, who was born and educated in York, is sixth richest on the list thanks to his stake in pharmaceutical company Bioglan Pharma which has netted him a £250m fortune.

Mr Sadler, who is 52, famously raised the final £30,000 he needed to buy the firm in 1982 by using his credit cards - 16 years later the company floated on the stock market valued at £193m.

The list of the 200 richest people in the region, which is published in the latest issue of the magazine, reveals Yorkshire's combined wealth totals an astonishing £10.66 bn.

Philip Beresford, who compiles the Sunday Times annual list of Britain's 1,000 richest people and who helped compile the Insider analysis, said the Yorkshire list is dominated by male millionaires.

"Only six women make the 200 list in their own right; among them are Janet Drinkall and Suzanne Marshall who own York-based Phoenix Software," he said.

"They have shown that gender is no barrier to a thriving software business."

The York-based Shepherd family are prominent on the 200 list; Shepherd Building Group is estimated to have £151m of net assets while the family are estimated to have a fortune of £9m at their disposal.

Finally Hamish Ogston, who is worth £125m, made his fortune by founding the Card Protection Plan in 1980.

Now more than 80 per cent of card issuers promote CPP and last year CPP Holdings moved from its London office to headquarters in Holgate Park, York.
