The son of a millionaire businessman at the centre of a paternity row has broken his silence to say his father is "very manipulative" and "not the kind of person you want to be with". Joel Mason, 19, revealed he has no plans to learn who his biological father is and that he hasn't spoken to Richard Mason for three years. Now he has spoken out about his strained relationship with the co-founder of price comparison website MoneySupermarket.com, who he believed was his father for 21 years.
