Prince William

THE second-in-line to the throne was paid £44,000-a-year for his part-time job as a helicopter pilot, which he gave up earlier this year. He receives around £300,000 a year in interest payments from his mother’s £10 m legacy, plus a share of the £3.2 m which his father gives to him and brother Harry annually. If we assume that’s divided equally, he has an annual income of £1.94 m.

HOW HE SPENDS IT: Well, polo kit doesn’t come cheap. He’s also a fan of Gieves & Hawkes tailoring and Ray-Ban shades.
