Stagecoach tycoon Brian Souter's fortune has soared during the economic downturn - with his "recession-proof" investments now worth £400 million. Mr Souter revealed the value of his fund has rocketed by 41 per cent in just three years.
His family's Souter Investments has a 14 per cent holding in Stagecoach - as well as undisclosed stakes in firms including insurance giant esure and price comparison website gocompare. The portfolio's value has grown from £250 million in 2007 to £400 million today.
Mr Souter - whose joint wealth with Mrs Gloag was put at £610 million in the 2010 Sunday Times Rich List - said: "The reason the value has risen is the type of investments we had were quite recession-proof. Souter Investments also has stakes in bus maker Alexander Dennis, luxury yacht company Sunseeker International and biodiesel firm Argent Energy.
