The Guardian published 15 different poll results yesterday, all predicting a Tory win
Hung parliament -
the YouGov model
This is the most recent forecast (from yesterday) from the YouGov model
, a forecasting model devised using multilevel regression and post-stratification (MRP). This involves taking polling data and, using data about the demographic composition of constituencies, and how different demographics vote, developing a seat-by-seat forecast. The
Conservatives (304) would have the most seats, but even with Northern Ireland unionists (around 10) they could be outvoted by a coalition of Labour (266), the SNP (46), the Lib Dems (12) and the Greens (1).

New Statesman
This is the majority implied by the seat forecasts in the New Statesman’s model, which takes the latest polling figures and produces a forecast using the RegVar forecasting model.
Conservative majority of around 40 - Peter Kellner’s prediction
This is the prediction that Peter Kellner, the leading pollster and former YouGov president, set out
in an Evening Standard column yesterday.
Conservative majority of 48 - Local election projection
This is the forecast that Sky New elections expert Prof Michael Thrasher produced straight after the local elections, judging what would happen in a general election based on voting in the locals. It does not take into account developments since the campaign started.
Conservative majority of 52 - Projection based on
Opinium’s final poll
Opinium’s final poll suggests the Tories are on 43%, Labour 36%, the Lib Dems 8% and Ukip 5%, and
Electoral Calculus says this would give the Tories a majority of 52.
Conservative majority of 58 - Projection based on “poll of polls”
in Guardian poll tracker
The Guardian’s poll tracker currently has the Tories on 44%, Labour on 36%, the Lib Dems on 8%, Ukip on 4% and the Greens on 2%,
and Electoral Calculus says this would give the Tories a majority of 58.
Conservative majority of 64 -
the Ashcroft Model
This is the central forecast of the Ashcroft Model, a forecasting model devised by Lord Ashcroft also using MRP. But his forecast is different from YouGov’s.
The Conservatives remain on course to win a majority in the general election, according to new figures from the Ashcroft Model. Our “combined probabilistic model”, which calculates the sum of each party’s win chances in all the seats in which it is standing, estimates 357 Tory seats, or a potential majority of 64 (up four from the previous update published last Friday). However, this central estimate, based on an update survey conducted over the weekend, combines the data from three different turnout scenarios: including all those who currently say they will vote on Thursday (giving a Conservative majority of 70); including all those who say they voted in the EU referendum (a Conservative majority of 48); and assuming turnout matches that of the 2015 election (a Conservative majority of 78).
