As an update:
My policy is to no longer report on polls by #WhitestoneInsight. This decision was reached after asking them why they hadn't published tables for a poll they conducted last month about the deselection of a Lib Dem parliamentary candidate. Their response was to publish the tables (meaning they hadn't complied with their BPC duty to do so until challenged) and the tables show that the question asked was one of the most (mis)leading push polling questions I've seen in my life.
