Can the Minister give the House an assurance that before any business rate changes are made that there will be a general rating revaluation? Is he aware that in Liverpool no revaluation has occurred since 1972? We now have the third highest business rate of any of the 36 metropolitan districts, and stores such as the city centre Marks and Spencer are paying the same rate as Marks and Spencer in Marble Arch in London. Does the hon. Gentleman agree that there is a good case for rate relief to he given to businesses in cities such as Liverpool?
