A recent investigation has revealed that a surrogate baby is born in India to a British couple every 48 hours.
An investigation has exposed the full extent of India's surrogacy baby boom driven by demand from childless Westerners.
One British couple who took advantage of India's "baby factories" have told of their joy at having twins through a surrogate.
Louis and Freya are the genetic offspring of Chris Morrison, 40, and his wife Susan, 37, but were carried by a Gujarati housewife.
Their case is expected to encourage thousands of childless couples to use Indian surrogates.
Dr Anita Soni, an obstetrician at a top Mumbai hospital, said: "I deliver babies from Indian women for British couples at the rate of more than 15 a month."
Dr Soni spoke minutes before entering the delivery room at the state-of-the-art Dr LH Hiranandani Hospital.
