First combined forecast for the 2024 general election

By Stephen Fisher, John Kenny, Paul Furey, and Polina Ryzhuk. 30th May 2024.

Here we combine seats and vote share forecasts from a variety of sources including betting markets, polls, statistical forecasting models, and citizen forecasts. As well as updating weekly, incorporating new forecasts with different methods as they become available, there may be developments in the methodology. Comments welcome. 

All the different sources of seat forecasts in Table 1 point to a very large Labour majority, well over 100.

How did the election forecasts do in 2019?

By Stephen Fisher, John Kenny, and Rosalind Shorrocks. 29th May 2024

Pretty well. Whereas many of the forecasts for the 2017 British general election incorrectly pointed to a Conservative majority, and sometimes a large one, in 2019 the general election forecasts correctly suggested a comfortable Conservative majority. But they did not do equally well and there are perhaps lessons to be learned for which forecasting methods might be more prescient than others this year.

Local elections 2024 summary (Saturday 4th May)

What we know at 8.20pm on Saturday 4th May 2024, after 106 out of 107 councils, 2640 councillors, 11 Mayoralties (including London and estimated West Midlands result), 35 out of 37 Police and Crime Commissioners (PCC), the Greater London Assembly (with all votes declared but not the D’Hondt allocation), and 1 parliamentary by-election. Just 1 council and 2 PCCs to declare.

Verdict: 

Extremely bad for the Conservatives. Good for Labour and Lib Dems. Very good for Greens. Mixed for Reform UK.

Conservatives:

  • Dropped to 25% in the BBC Projected National Share (PNS) of the local election vote: their joint lowest since records began in 1982
  • Lost control of 10 councils out of 16 they were defending: Adur, Basildon, Dorset, Dudley, Gloucester, Havant, North East Lincolnshire, Nuneaton & Bedworth, Redditch and Rushmoor.
  • – 473 net council seat losses: 48% of the 986 they defended, leaving them behind the Liberal Democrats in total seats won.
  • Won only 1 of the 11 directly elected Mayoralties, with Andy Street narrowly losing the West Midlands and Ben Houchen suffering a 17-point swing to Labour in Tees Valley.
  • Lost 10 of the 27 Police and Crime Commissioners they defended, with an average drop in vote share of 8 points across the 27.
  • Lost the contest for London Mayor with a 3-point drop in their share of the vote.
  • Lost 1 seat in the Greater London Assembly after a 3-point drop in their London-wide list vote.
  • Lost the Blackpool South by-election on a 26% swing (the third biggest by-election swing in the post-war period).

Labour:

  • First place with 34% in the BBC Projected National Share (PNS) of the local election vote: down 1 point on last year, but another 9-point lead over the Conservatives. Not as good as Labour achieved before their 1997 victory, but better than at any set of local elections where they went on to lose the general election.
  • +8 net gains in council control. Gained 10 (Adur, Cannock Chase, Hartlepool, Hyndburn, Milton Keynes, Nuneaton & Bedworth, Redditch, Rushmoor, Tamworth and Thurrock), but lost Kirklees and Oldham. Retained control of a further 40 councils.
  • +185 net council seats gains
  • Won 10 of the 11 directly elected mayor positions, including West Midlands from Andy Street and London, that is all but Tees Valley which Labour failed to take despite achieving a 17-point swing there.  
  • +10 gains of Police and Crime Commissioners, and held all 10 of those they were defending. Average vote share increase of +8 points across all 35 contests.
  • Won the London Mayor contest for the third time in a row, with an increased vote share of +4-points.
  • Maintained their position as largest party in the Greater London Assembly with 11 out of the 25 seats.
  • Won the Blackpool South by-election on a 26% swing (the third biggest by-election swing in post-war period), in line with other big by-election wins for Labour this parliament.

Liberal Democrats:

  • Gained control of Dorset and Tunbridge Wells and held all 10 councils they were defending.
  • +104 net council seat gains, winning 521 seats in total (more than the 513 secured by the Conservatives). 
  • Increased vote share +3 points on average across the Police and Crime Commissioners, despite the change in the electoral system creating incentives for their supporters to vote tactically away from them in most places.
  • Maintained their position in the Greater London Assembly with 2 seats.

Green Party:

  • Secured their best local elections performance ever (better than 2019): enough to put them at 13% in the local elections Projected National Share (PNS)
  • +74 net council seat gains, winning 181 seats in total 
  • Averaged 15% across the 7 Police and Crime Commissioner positions they stood for, despite the change in the electoral system creating incentives for their supporters to vote tactically for others
  • Maintained their position in the Greater London Assembly with 3 seats.

Reform UK:

  • Came 3rd on 17%, narrowly behind the Conservatives, at the Blackpool South by-election.
  • Won just 2 council seats out of 2640 up for election.
  • Averaged 12% of the vote, in the wards they contested, but they contested just 12% of seats.
  • Put in a much more limited effort and much less impressive performance than UKIP did in local elections between 2013 and 2016.
  • 1 seat on the Greater London Assembly with 6% of the vote.

Understanding the Local Elections Projected National Share (PNS) in 2024

by John Curtice and Stephen Fisher, 1st May 2024.

Seats won and lost in the local council elections in England this week may be a poor guide as to how well the parties performed. Since the elections are held under single or multi-member plurality, without any increase in support a party may make big gains in seats off the back of another party losing votes. A third party whose vote is geographically spread may make a substantial advance in votes yet reap little reward in terms of seats. Meanwhile, seats won and lost only provide an indication of whether a party has lost or gained ground as compared with when the seats up for grabs were last contested.

These caveats are important again this year. Around 70% of the council seats up for grabs this year were last fought over in May 2021. Boris Johnson was Prime Minister and the Conservatives were successfully claiming the credit for an early Covid vaccine rollout. The party enjoyed a six-point lead in the polls, gained over 200 seats in the local elections and recorded their best performance in terms of votes since 2017.

The Conservatives therefore face the challenge this week of defending a strong baseline while running 20 points behind in the polls (an even weaker position than this time last year). They look set to make significant losses. Other parties, such as the Liberal Democrats, may gain seats purely as a result of the decline in support for the Conservatives, without necessarily attracting more voters themselves.

That said, one key uncertainty is that Reform UK are only fielding candidates in one in six of the wards where local elections will take place. According to the polls, the Conservatives are now losing more of their 2019 voters to Reform than any other party. Perhaps some of these voters will switch to the Conservatives where Reform are not on the ballot paper, thereby helping to stem Conservative losses. 

Yet we cannot assess party performance by simply adding up the votes cast (even if we had the resource to collect them all on election night). In England (unlike Scotland and Wales) it is never the case that the whole country votes in local elections at the same time. The places that vote one year are politically different from those that vote in another.

Local election seat projections for 2024

By Stephen Fisher, 1st May 2024.

Changes in vote intention opinion polls typically provide an indication of headline net seat changes at local elections. Most of the seats up this year were last fought in 2021. The following table shows how party support in the opinion polls has changed since then.

Table 1. Opinion poll changes from 2021 locals to 2024 locals

%2021 polls2024 pollsChange
Con4123-18
Lab3644+8
LD79+2
Reform312+9
Green56+1

Those changes imply a 13-point swing from Conservative to Labour. The graphs below show broadly how that might translate into seat gains for Labour and losses for the Conservatives as percentages of the 2650+ seats up this year. The 13 point swing should put this week’s local election results on par with those for 1995, 1996 and 2013.

Liberal Democrat local seat tallies at the national level have historically been linked primarily on the swing between them and the Conservatives. That swing is 10-points to the Liberal Democrats this time. 

Table 2 below shows predictions from the regression models. The figure for Others is just an accounting balance. The Conservative and Labour models are based on Con-Lab swing and the Lib Dem model is based on Con-LD swing. The three are estimated separately. They do not take direct account of the rise in the Reform party share, nor perhaps more importantly given their success last year, the big rise in the number of Green party candidates relative to the number of seats up for election. 

Table 2. Model based forecasts for English local election net seat gains/losses for 2024

 Forecast
Con-390
Lab+320
LD+100
Others-30

Based on last year’s experience, I would expect the Conservatives to do worse than the model suggests, and the Liberal Democrats and Others (mainly Greens) to do better.
