there was concern that the referendum forms were confusing. a dedicated council help line received 943 calls in one day. there were complaints that the question was biased, referring to the council's "preferred" strategy and there were concerns expressed by some political parties that the information leaflet enclosed with the form would also add to the confusion. around 30,000 residents who had stated a preference not to receive junk mail on the electoral register form could not be sent a ballot form.
