The British Polling Council (BPC) welcomes the unveiling today of the provisional findings of the Polling Inquiry on why the polls overestimated Labour and underestimated Conservative support in last May’s general election. Though established shortly after the last election by the BPC in collaboration with the Market Research Society, the Inquiry has been working wholly independently of its sponsors under the chairmanship of Prof. Patrick Sturgis of the University of Southampton. The Council is deeply grateful to Prof. Sturgis and his colleagues for the work they have undertaken so far and looks forward to receiving their final report in March.
Prof. John Curtice, President of the British Polling Council, said, ‘Today’s unveiling will provide the polling companies and everyone else with an interest in its work to hear and respond to the Inquiry’s initial conclusions. It hopes that this process will prove helpful to the work of the Inquiry and ensure that its final conclusions are based on the strongest possible body of evidence.’
