 Due to the overall yield being linked to the Retail Prices Index as a measure of inflation, the contribution of business rates to local government finance has decreased compared to Council Tax and government grants.Many local authorities have called for the rate to be increased, and for the power to set the multiplier to be returned to local control; both suggestions have been opposed by business organisations such as the British Retail Consortium.The Lyons Inquiry rejected the return to local control, and instead proposed giving local authorities the power to levy a local supplement, in consultation with affected businesses; responses from the business sector have ranged from caution to opposition.
