Moneysupermarket.com founder Richard Mason was shocked to find his kids aren’t his after 21 years, the Mail On Sunday reports.
Mason was told he had genetic disorder cystic fibrosis, meaning he had been infertile all his life and was duped by Ex-wife Kate, who confessed to having an on-off affair but didn’t name the lover.
After they divorced in 2006 he gave her a £4m settlement and paid £3,000 a month to help bring up the children. She has now been ordered to pay him back £250,000 after a court battle.
Mason is now offering a £5,000 reward for information to discover the identity of the real father.
