The article below signals that the plan to replace grant income with 100% business rates devolution looks like hitting the buffers on a permanent basis.  Ultimately I  think common sense has prevailed . Business rates is an archaic system which needs reform at source . Using it as a proxy for grant and proposing a byzantine allocation system based largely on the current grant redistribution process was never going to work .  A better solution would be to allow a range of local taxes ( including council tax revaluation - how can it be sensible to use a baseline set in 1991?) supported by needs based grants.
