BPC/MRS Polling Inquiry

The pre-election polls significantly under-estimated the size of the Conservative lead over Labour at the 2015 General Election, with nearly all the final polls calling the ‘horse race’ as a dead heat. The failure to predict the Conservative majority has led many commentators to question the value and robustness of polling methodology, with some even calling for polls to be banned in the final weeks preceding an election.

In response to these events, the British Polling Council and the Market Research Society have instigated an independent inquiry into the causes of the discrepancy between the final polls and the election result, to be chaired by Professor Patrick Sturgis of the University of Southampton.

This is the website for the inquiry. Here, interested parties can submit evidence for consideration by the inquiry panel. Information about the inquiry will also be made available on an ongoing basis.
