Tens of millions of pounds of UK aid money have been spent on a programme that has forcibly sterilised Indian women and men, theObserver has learned. Many have died as a result of botched operations, while others have been left bleeding and in agony. A number of pregnant women selected for sterilisation suffered miscarriages and lost their babies.

The UK agreed to give India £166m to fund the programme, despite allegations that the money would be used to sterilise the poor in an attempt to curb the country’s burgeoning population of 1.2 billion people.

Sterilisation has been mired in controversy for years. With officials and doctors paid a bonus for every operation, poor and little-educated men and women in rural areas are routinely rounded up and sterilised without having a chance to object. Activists say some are told they are going to health camps for operations that will improve their general wellbeing and only discover the truth after going under the knife.
