Harriet Harman, the Women's Minister, is to visit Sweden with other ministers to find out how a similar scheme works over there.
She says: "Unless you tackle the demand side of human trafficking which is fuelling this trade, we will not be able to protect women from it.
"Do we think it's right in the 21st century that women should be in a sex trade, or do we think it's exploitation and should be banned?"
It's estimated that up to 85% of the approximately 50,000 prostitutes in Britain are foreign, and large numbers of them are brought here illegally.
Many face appalling conditions, violently and brutally treated by the men who've smuggled them into the country and keep them in a state of virtual imprisonment.
I've written about prostitution before, putting the case for banning it and the case for legalising it. It's very difficult to decide which is the best course to follow.
Already Harriet Harman has her critics who don't think banning payment is the way to go. They say all that will do is push the business further underground, which in their opinion is what's happened in Sweden.
Some people favour the opposite approach of totally decriminalising buying and selling sex, as was done in New Zealand.
Others again say the legal position is beside the point, what prostitutes really need is practical help and support to give up prostitution and get into a more dignified and worthwhile occupation.
But it's encouraging that a government minister is concerned enough about the situation to look for new ways of dealing with it and ending the misery and degradation it so often involves.
PS: I'm off to London this afternoon to visit my 85-year-old mum. Back in a few days. I look forward to reading all your comments!
