Forecast update: 10 October 2014

Forecast b 141010

After falling to their worst forecast yet last week, the Tories have recovered to retake the lead, although it’s still looking very close.

This week’s average is the first to include the post-Tory conference polls, and sees them move up 1 point to 32%, while Labour drop 2 to 34%. There was some sign of a bounce for the Tories following Cameron’s speech, but it seems to have died away since. Still, Labour’s 2-point lead is one of the smallest we’ve seen since early 2012.

The Tories’ chances of winning the most seats in May are back up to 53% (from 41% last week), while Labour’s are down to 47% (from 59%). The likelihood of a Hung Parliament continues to rise, to 54% this week – the highest since our forecast began 12 months ago.

Our central forecast is for the Tories to win 299 seats to Labour’s 293, leaving them 27 seats short of a majority (with the Lib Dems winning 28).

Following the Clacton by-election, our model now forecasts UKIP to hold that seat at the General Election (included in the ‘others’ total on our chart). However – on semi-uniform changes – it doesn’t have them down to win any others (though in reality they could get a handful).

  1. These poll are crap and useless, its the truth and unless you make proper changes your end up looking like fools.

    There is a high chance the SNP could take 10-20 seats in Scotland, Its also very possible UKIP could gain 10 seats in England.

    I also believe there is more chance of a Labour being the biggest party since alot of Lib dem voters will switch back. what can you do.
