And the BPC announces details of its GE15 inquiry
After every general election Ipsos produces a table like the one above which become a key source of reference.
Meanwhile the British Polling Council has announced details of its inquiry into what went wrong with the polls.
Under the chairmanship of Prof. Patrick Sturgis, Director of the National Centre for Research Methods at the University of Southampton, the Inquiry is charged with the task of establishing the degree of inaccuracy in the polls, the reasons for the inaccuracies it identifies, and whether the findings and conduct of the polls were adequately communicated to the general public. Due to report by 1 March next year, the Inquiry will seek and welcomes submissions from all interested parties, and is empowered both to make recommendations about the future practice of polling and, where appropriate, for changes in the rules of the BPC. The BPC and MRS are committed to publishing the Inquiryâ€™s report in full.
