The Institute for Public Policy Research is promoting the idea that big cities like Liverpool, Birmingham and Manchester should have their own mayors with tax raising powers. The London Mayor has increased his precept by 175% in seven short years. Luckily he collects this cash from us through the council tax, so whilst we feel poor at least we have jobs. The IPPR are suggesting a levy of 5% on business rates for our other great cities. No jobs north of Watford Gap then.
