Dude, I mentioned that NI was an exception way back in my original post: https://news.ycombinator.com/item?id=14066425 So you really don't need to point that out to me!

>He said there were two prostitutes listed as guests, and that they advertised their services and rates online, which can be classed as solicitation.

You have a kind of genius for spreading inaccurate information. Advertising yourself as a prostitute online is not illegal in Britain and is not classed as solicitation.

To prove that a crime was committed, the police would have to show, at minimum, that both of the women actually had sex with a client in the same property. That is obviously not going to be possible.
