Roger Federer isn’t just one of the greatest tennis players of all time - he’s also one of the richest. BBC business editor Simon Jack and journalist Zing Tsjeng follow his journey: from a fiery, racket-smashing junior in Switzerland to the calm, composed global icon who conquered Wimbledon, and the world of endorsements.

Good Bad Billionaire is the podcast that explores the lives of the super-rich and famous, tracking their wealth, philanthropy, business ethics, and success. There are leaders who made their money in Silicon Valley, on Wall Street and in high street fashion. From iconic celebrities and CEOs to titans of technology, the podcast unravels tales of fortune, power, economics, ambition and moral responsibility. Simon and Zing put their subjects to the test with a playful, totally unscientific scorecard — then hand the verdict over to you: are they good, bad, or simply billionaires?
