Reforms to prostitution laws
An expert group was assembled in 2003 and produced a report in 2004 entitled Being Outside - Constructing a Response to Street Prostitution. The key proposals included replacing soliciting laws with 'offensive behaviour or conduct', applicable to both buyer or seller (obviating pressure to criminalise kerb crawling), and 'managed areas' in which the activity would take place. They also recommended a national framework to guide local authorities, a requirement for local implementation plans, and public education. 
A Prostitution Tolerance Zones Bill was introduced into the Scottish Parliament but failed to become law. Instead, the Parliament passed the Prostitution (Public Places) (Scotland) Act 2007 which leaves the law relating to prostitutes unchanged but introduces a new offence committed by their clients.
In April 2010, a plan to criminalize the customers, which had been introduced by Labour politicians, was rejected. A further attempt by Marlyn Glen (Labour) to introduce this (amendment 6) at Stage 3 was also voted down 78: 44 on June 30, 2010. 
A further attempt by Trish Godman (Labour) was made in 2011 but fell at dissolution. Yet another attempt was made by Rhoda Grant (Labour) was made in 2013 but was only supported by Labour MSPs and therefore did not receive cross-party support.
