Surrogacy law change urged as baby left behind

There are calls for a change in surrogacy laws, after an Australian couple left their baby in Thailand because he had Down's Syndrome.

Gammy's natural parents left him with surrogate mother Pattaramon Chanbua, but took his healthy twin sister.

Nicola Scott of Natalie Gamble Associates says laws on surrogacy vary from country to country, leaving children vulnerable.
