Stories have been emerging for some time of promiscuity in the 24-hour call centres. There was the centre where the drains were choked with condoms.

And the call centre worker who told the press she and her colleagues went to work with condoms in their handbags.

Hardly a cause for concern by western standards. But in India, where attitudes to sex remain highly conservative, and an unmarried woman can still get in trouble for just being seen talking to a man, it has caused something of a minor scandal. Which is where the Catholic church has come in, offering counselling and week-long retreats for call centre workers "in the hope of turning staff away from a life of sin".

"We don't want to do moral policing, " the Archbishop of Bangalore, Bernard Moras said. "But we want to advise young people that being 'modern' doesn't mean losing their family traditions or moral values. We are responsible for these young people. We have to show them we care by giving them guidance and showing them the dangers of adultery and casual sex."

There is a sexual revolution going on in India. Today's young middle class Indians date in a way their parents could never have dreamed of. In the major cities, more and more nightclubs and bars are opening up where men and women can socialise freely. In Delhi this year, plastic surgeons say they have seen a 40% rise in demand for cosmetic surgery in the lead up to this weekend's Diwali festival. A survey of call centre workers last year found that 38% believed that premarital sex is morally acceptable and a quarter regularly had casual sex.

The Catholic church can hold its retreats, but it looks like the sexual revolution has got hold of India.
