On June 17 Ruth Wyner and John Brock will have been in prison for six months. Their crime: running a charity for the homeless where some clients were secretly exchanging drugs on the premises.

There has been a call for a change in the law because this case affects so many people in this area and throughout the country who are working with vulnerable clients.

Meanwhile Ruth and John remain in prison. To offer them support or for further information please contact: The Cambridge Two Campaign, 6 Hertford St, Cambridge CB4 3AG or www.cambridgetwo.com
