What went wrong with the opinion polls

Dr Stephen Fisher is a Associate Professor at the Department of Sociology, and has been involved in election predictions for the past twenty years.  His well-regarded blog, Elections Etc, drew data from a range of opinion polls in the run up to the 7 May 2015 UK General Election, and he worked closely with the team behind the exit poll that surprised pundits and the public alike with its prediction of a Conservative majority.  

Dr Fisher and a colleague, Dr Chris Hanretty at the University of East Anglia, recently gave a talk that discussed these contrasting polls.
