Nick Clarke in a recent blogpost said:
"I made the point that whilst I am not an expert on planning I do have the largest democratic mandate, representing all 680,000 people of Cambridgeshire."
Nick isn't directly elected. Nor was Nick leader at the time of the last County Elections in 2009. Therefore he doesn't have a mandate. If Nick held a referendum over Council Tax increases he would have a mandate to increase these taxes. He won't do that. If Nick gets a majority on 2nd May 2013 he may also have a mandate. Until then Nick doesn't have a mandate for anything!
