Veteran star Paul Anka is facing legal action from Mohamed Al-Fayed over allegations the singer defamed the former Harrods boss in his autobiography.

Al-Fayed maintains Anka portrays his son Dodi Fayed, the lover of late British royal Diana, Princess of Wales, in a negative light in his new title My Way.

The billionaire tycoon also claims the book contains false stories about the businessman repeatedly bailing Dodi out of trouble, but Anka is standing by the accounts in his memoir, telling, "We have the evidence. We're very confident in this. Everything is true."
