The rags to riches story of the billionaire brothers from Blackburn, Lancashire who have grown their business from a single petrol station in 2001 to a global empire of six thousand garage forecourts in less than twenty years.

Notoriously private, the brothers became national news last year after buying the supermarket giant, Asda. Last week they added the fast-food chain, Leon, to their portfolio. And now they’re rumoured to have their eye on Caffé Nero.

Talking to family, friends and business associates, Mark Coles discovers how different the brothers are, what fuels their passion for petrol stations and how they cope with media attention.
