Local Government Finance

I share the hon. Lady's experience of being a council leader under the Conservatives, so I can certainly corroborate what she said about that. Is not one of the problems with revaluation that the longer it is left, the more out of kilter it gets, so that when the resultant rises inevitably come, they are even bigger for the losers in the system? We have waited 20 years, so values are 20 years out of date. Are we going to wait for them to become 100 years out of date before somebody dares to carry out a revaluation or are we going to do the sensible thing, which is completely to change the basis of local government taxation?
