Thai surrogate baby Gammy: Australian parents 'wanted him'

The Australian couple accused of abandoning a baby born with Down's syndrome to a Thai surrogate mother say they wanted to take him home.

David and Wendy Farnell, speaking publicly for the first time, insisted the Thai mother would not hand over Gammy, now seven months old.

The couple, who took Gammy's twin sister, say they want to get him back.
