Richard Wilson appears to be against decriminalisation of sex work, he posted a some what derogatory response to a Liberal Democrat who asked him his views on decriminilisation of sexwork. Richard Wilson does not appear to know the current status of sex work in this country.
Richard Wilson’s blog post is here http://wilsonrichard.com/2015/04/05/potter-gate-the-guildford-lib-dem-candidate-with-too-much-interest-in-me/
I would suggest that this MP would support further criminalisation of sexwork, including criminilising clients and increased criminalisation of those working together.
There are certainly *some* arguments for legalising prostitution in certain areas – I personally wouldn’t support that in Guildford. Also, the email proposes decriminalising the clients, not “cracking down”.
A good take down of his article by a labour supporter is written here https://sometimesitsjustacigar.wordpress.com/2015/04/05/slander-smears-and-small-minds/
