He's spent a billion on Manchester United, but how did Jim Ratcliffe become a billionaire?

BBC business editor Simon Jack and journalist Zing Tsjeng learn how the Premier League club's new co-owner got rich via some daring investments and impressive acquisitions. They explain how he made his name in petrochemicals before founding Ineos, one of the industry's biggest conglomerates.

Simon and Zing also discover that he mortgaged his own house to fund a business, as well as uncovering his investments in cycling, sailing and, of course, football. Then they decide if he's good, bad, or just another billionaire.
