When I visited the Rutherfords I promised them that if Labour won the election, cancelling the bedroom tax would be the first thing I did. When I saw the exit polls at 10pm on 7 May I thought of Warren and his grandparents. I felt we had let them down and I feared what another five years of Tory government would mean for them and the other 500,000 households paying the bedroom tax. On Tuesday, Paul and Sue got a rare piece of good news. They took the government to The Court of Appeal - and won, with the Judge concluding that the bedroom tax is unlawful because it discriminates against disabled children and in a separate case against the victims of domestic violence.
