PRS homes can not be treated as social housing, so this Labour munchkin is spouting nonsense; however PRS homes do have to be fit for purpose under existing trading laws, and also fit for health under existing environmental health laws.
What is deficit then is tenant access to have such laws applied and upheld in an age where access to the law is dependent upon your ability to fund legal actions without state support. Perhaps the Labour Party could look at this area of attack against the working class, and restore housing advice and legal aid access.
Then, restoring other rights and legal protections for working people would be a natural step, as would restoring the provision of social housing for rent.
What the little thinker is perhaps not understanding is the implication and outcome of the ditching of Clause 4, and how that has participated in the imbalance we know experience, and removed the means with which to address it.
