David and Wendy Farnell, the couple criticised for allegedly leaving a baby boy with Down's syndrome in Thailand but taking his healthy twin sister home, have given their side of the story to Australia's 60 Minutes.
David Farnell breaks down as he explains: "The surrogate mother wanted to take our girl - and we were getting scared that we would lose her."
That was the reason the couple left baby Gammy behind with the surrogate, the 56-year-old told the programme.
David Farnell also admitted in the interview, which was broadcast on Sunday night in Australia, that he had been convicted of child sex offences in the past.
