Wylie, 44, retired last year from Sage Group, the Newcastle upon Tyne software firm he co-founded - but did not put his feet up. First there was his wedding to Andrea Storey, a hairdresser, at which the Irish pop star Ronan Keating was paid £200,000 to sing. Then he sold a large chunk of his Sage holding, netting £116.5m before tax. He used some of the money to buy a small information technology company. Wylie retains a stake in Sage worth £75m.
