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.

In the headline prediction table, the columns 'Low Seats' and 'High Seats' give the 90 per cent confidence interval for the number of seats won.

Commentary on September 2021

Posted 4 October 2021

Labour gained some support on average in September, as our poll-of-polls shows them up 2pc on 35pc, while the Conservatives remain constant on 40pc. This may be due to the government's announcements of higher taxes, plus worries about the economy and extra publicity for Labour from their party conference.

The Conservatives will have their change for a party conference bounce in the October polls, but the overall political situation is getting more competitive than it has been during the Covid period.

If there were an imminent general election, these poll results would translate into a Conservative majority of twenty seats, which is workable but much less than they won in 2019.
