Dr Stephen Fisher explains what went wrong with the opinion polls

Last week, Stephen Fisher and Chris Hanretty (University of East Anglia) gave a talk at Merton College entitled 'Interpreting the UK election results and why the opinion polls got it wrong'.  Both Stephen and Chris worked on (separate) polls that were the basis for many people's predictions on the election result, and Stephen was a member of the team that produced the exit poll that proved such a surprise to pundits and public alike.
