This came up on Any Questions on Radio 4. What's interesting is the general flailing about regarding the topic. Harman has long been completely anti, it's almost an obsession with her, but other politicians sidestep. Eg; "I support personal liberty and choice but........I'm a Catholic." Or some such nonsense.
As has been said, prohibition doesn't work. I welcome the time, if it ever comes, when there's German style clubs in London.
The only party, Harriet Harman aside, who will ever be inclined to liberalise the law on prostitution is the Labour Party but they now have a bearded fuck wit as leader who stands even less chance than Miliband.
And the Lib Dems? Be serious.
So we wait. And wait. Prostitution will always be a back burner issue.
