There has been huge success in devolution, and I am a massive fan of a great deal of what the Parliament has achieved, but the reform of council tax is a long-standing failure of multiple sessions and multiple Governments.The idea of levying a property tax based on property values set in 1991 is absurd enough in itself, but how long do we allow that situation to continue? If 35 years out of date is not bad enough, will we allow it to be 40 years out of date, 50 years out of date or 60 years out of date?
