Latest Forecast from Stephen Fisher Forecast b 140919
After losing their lead in our forecast last week, the Conservatives have rebounded this week for their strongest forecast in two months.
In the UK Polling Report Average, the Tories have recovered the point they lost last week, back to 33%. Meanwhile Labour have lost a point for the first time since the beginning of July, to 35%. (UKIP are down two, to 13%.) The two-point gap is the closest the Tories have been since early-2012, with the exception of a single week in mid-May when they were just a point behind Labour.
That puts the Tories back in front in our forecast, with their chances of winning the most seats rising from 48% to 56%, their highest since mid-July. Labour’s chances are down from 52% to 44%.
It’s still very finely-balanced, with a 51% chance that neither party gains a majority (down a touch from 52% last week). Our model gives the Tories a 29% of winning a majority (up from 22%), and Labour a 20% chance (down from 26%).
Our central forecast is for the Tories to win 303 seats (up from 295 last week), leaving them 23 seats short of a majority. Labour are 11 seats behind on 292, down from 299 last week. In that scenario, the Lib Dems get 26 seats with 11.5% of the vote, enough for a very slim majority coalition with the Conservatives, but not with Labour.

  1. my god i have read loads of drivel but this takes the biscuit. You lot need to get a life and stop indulging in make believe

    1. The drivel as you call it, is from a Oxford Professor, so is educated drivel. I for once agree with you in respects of I find it highly unlikely that the Conservatives would have a majority, they would struggle to get to be the largest party. But this is Prof, Fishers findings and he has laid them out eloquently. I would be pleased to see your information. I myself see Labour getting at least 290 seats nailed on, its just the ones to get them across the line which will be the interesting factor. As proven before though, Ed is Labours biggest problem. Will he be the factor and is he the factor that makes Prof Fishers forecast correct?
