The future is never certain. But using our advanced modelling techniques, we can estimate the probability of the various possible outcomes at the next general election. Minority government probabilities assume possible alliances between the Conservative and Reform parties, and between Labour, Liberal Democrats, SNP and Plaid Cymru.

Labour has bounced back into an overall majority, with Reform now pushed into fourth place behind the Liberal Democrats.

These figures include adjustment for tactical voting, as described here.

Technical note

This month, the central forecast number of seats for the Green party is two, which is outside the 90pc confidence interval which runs from 3 to 40 seats. Although this looks strange, it's actually correct. Here's why.

The figure of two seats is the number the Greens are predicted to win under the central forecast, using the expected number of votes in each seat. But there is a difference between seat winners and expected seats. The Greens have a fair chance of winning many other seats but they are not the likely winners in those seats. These do not count as seat wins in the central forecast but contribute to the expected number of Green seats, which is 14.7. And the confidence bounds surround this expected value as they should do.
