Alan Sugar buys stake in Woolworth's

Alan Sugar, the millionaire star of BBC’s 'The Apprentice', has bought a near-4% share in struggling retailer Woolworths, it emerged today.

His stake in the famous high street name is worth almost £2m at current prices.

The businessman – famous for his grilling of contestants and his “You’re fired” catchphrase – sold his Amstrad firm, which makes set-top TV boxes, to satellite broadcaster BSkyB last year.
