Speaking on the eve of the council tax revaluation date for homes in England and Scotland, Lib-Dem local government spokesman Edward Davey said: "Council tax is simply unfair. It hits pensioners and people on low and fixed incomes the hardest, and revaluationis going to make it worse. Council tax has already brought out the protesters, but with seven million families facing a 20 per cent or more hike in their bills, the protests are going to get worse.
