Disappointment for UKIP and Greens but SNP to be a major force in Scotland according to top figures from the worlds of academia, journalism and polling.


A new survey by the Political Studies Association asked a group of major political academics, journalists and pollsters in the United Kingdom for their election predictions.

The Political Studies Association today released the results of a survey of expert predictions for the 2015 general election. The survey was distributed to members of the Association as well as a large number of survey researchers from major polling companies in Britain and to political journalists from the print and broadcast media. The Association asked respondents to share their predictions on the vote share and seat numbers for each of the major parties in May’s election.

The result of the ‘Wisdom of Crowds’ expert prediction is:

  • Experts are predicting a tight race, with the Conservatives and Labour virtually inseparable in terms of both votes and seats: the Conservatives are marginally ahead on vote share (32.6% to 32.3%) and Labour are marginally ahead on seats (282 to 278).
  • Experts foresee potential disappointment for UKIP supporters, who are expected, on average, to pick up around 6 seats (with academics slightly more optimistic on UKIP’s prospects than journalists or pollsters). Experts also predict that the Greens will pick up just 2 seats.
  • Experts predict that the SNP will be a major force in Scotland, picking up 29 seats, but somewhat below the level of support they are currently polling.
  • Notably, the predictions of the three expert groups differ very little across the worlds of academia, journalism and polling.
  • Our expert predictions implicitly recognize the way in which the electoral system means Labour is likely to win more seats, even though it is expected to win fewer votes (49.4% of respondents believe the Conservatives will receive a greater share of votes than Labour, but only 36% believe that they will win more seats).
