Nadia shivers in the cold night air while waiting for punters on the streets of Oslo. Until recently, the centre of the Norwegian capital was the country's main red-light district, with sex workers standing at every corner waiting for clients.
But tonight the streets are almost deserted. Nadia, a year-old heroin addict, is one of only three prostitutes out working. There are few customers because, since 1 January, it has been illegal to buy sex in Norway.
Approximately 35 men have been fined so far - many caught in the act, as was one of Nadia's clients. She recalls: "We were busy when the police came - it was embarrassing. I told the guy he should say I was feeling unwell and that he was driving me home.
I stuck to the story, but he spilled the beans immediately. Norway is the latest in a small, but growing, number of European nations that have criminalised paying for sex. Sweden has had a ban on buying sex since , while in Finland it has been illegal since to buy sex from a woman who is trafficked or pimped.
England, Wales and Northern Ireland are now considering following Finland's example. The policing and crime bill that has just gone through the House of Commons will make it an offence to pay for sex with someone "subjected to force by psychological means and the exploitation of vulnerability".
