During the introduction of business rates, criticism focused on the level of the multiplier to be chosen, and on the transitional relief scheme, with organisations such as the Confederation of British Industry calling for a lower multiplier and a relief scheme more to the benefit of its members. In 2007, the Lyons Inquiry into Local Government said there was no significant opposition to the principles of the tax, but that the level was a concern to property-intensive businesses. 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.
