it's complete bullshit. firstly housebuilders in the uk, and this is just the majors, already have planning permission for 1 million new homes. secondly, if those homes were meeting domestic demand they might transform availability of housing. instead because no government in the uk is willing to see house prices fall, houses perform as a de facto currency for large wealth funds and kept in pristine condition with no residents.
every single person in the labour leadership who has ears has been told this repeatedly
