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, the man he grew up believing was his father, for three years.

Now he has spoken out about his strained relationship with Mr Mason, co-founder of price comparison website MoneySupermarket.com, who he believed was his father for 21 years.

Joel, along with his twin brother Ed and elder sibling Willem, 23, learned that Mr Mason had been infertile since birth after he was diagnosed with cystic fibrosis in 2016.

Their mother revealed she had a four-year affair during the 1990s and has now been ordered to pay her former husband £250,000 following an extraordinary legal case, which does not force her to reveal the true identity of her sons' father.

Speaking for the first time since the secret emerged, Joel described Mr Mason as "very manipulative" and said they had not spoken for years.

He admitted that he thinks his biological father doesn't know he and his brothers exist.
