I thank my noble friend, but how is it that a £12 million penthouse in Islington pays £1,000 less in council tax than a £1.5 million manor house in Hartlepool? It is eight times the value, yet it pays £1,000 less. This is why council tax is so regressive, and no tough decisions have been taken for 34 years. When people no longer know what a tax is for or how it is fixed, and they see this unfairness, that risks bringing the whole system into disrepute. It is a major political and social risk. Why are we taking it?
