There's a bit of hope in this one.
More women smuggled into UK for sex trade
Human trafficking has risen during the past few years
More than 4,000 women working in the sex trade have been brought into Britain for prostitution, Home Office figures show.
A study to be published in full later this year found there were around that many victims of trafficking for prostitution in the UK at any time in 2003.
Preliminary findings from the report, released to the Parliamentary Joint Committee on Human Rights, also state that human trafficking has increased during the past three years.
But Home Office minister Vernon Coaker insisted that demand for sex with trafficked women was falling.
He told the committee that a publicity campaign telling men they could be charged with rape if they pay for sex with a woman working under duress was influencing men's attitudes.
Police behind Operation Pentameter - a four-month crackdown which rescued 84 trafficked women from prostitution - have written to men's magazines and distributed leaflets to people going to the World Cup finals in Germany.
Mr Coaker said there was evidence that demand for sex with trafficked women had fallen as a result of "these messages that have been going out''.
He added: "We know that we need to do more with respect to many of these things, we know there are challenges that we have to meet.
"This is a new area of work. It's something that five, 10 years ago perhaps, people very rarely talked of. But it's a major challenge for us and we're determined to do what we can to beat it.''
