We’ve already had two focus groups published for the June Parliamentary by-elections in Tiverton & Honiton and Wakefield (short version: double grim news for the Conservatives), but this week has brought the first opinion poll.
Carried out by JL Partners for the Sunday Times, it shows Labour well ahead in Wakefield. It’s showing a big swing to Labour, one that would result in a headline-grabbing comfortable win, though also a swing still well short of the sort Labour was getting in the run-up to the last time it ousted a Conservative government (in 1997).
However, the poll is only one poll, taken several weeks before polling day. Constituency polling, moreover, has a pretty mixed record in British politics. Add to that the greater volatility of voters in the closing stages of a by-election rather than a general election, and it would be easy to present a superficially smart argument about how little to trust the poll.
The evidence, though, suggests otherwise. Let’s take a simple measure: did the last poll carried out in a Parliamentary by-election before polling day get the winner right or not? The score is 9 correct to 2 wrong in the 11 by-elections polled over the last decade. One of the two exceptions, moreover, was Richmond Park, where a poll taken early in the campaign – more than a month before polling day – was taken too early to pick up the big late surge to the Liberal Democrats. Even that, though, had got right that the Lib Dem vote was up sharply. Which leaves the one other error – Batley and Spen – where Survation’s poll seems to have been mostly undone by failing to pick up the support for George Galloway (6% in the poll, 22% in the result). Note that the Wakefield poll didn’t prompt for the Yorkshire Party, who are standing in Wakefield.
Also in the poll’s favour is that it fits with what we know from other polling. National polls have the Conservatives down over ten points and Labour up approaching ten points since 2019. Add in the usual exaggerations of by-elections, and the JL Partners figures look plausible for a by-election like this.
All in all, therefore, while it is just one poll, it’s a promising pointer, and more robust evidence than you often get from a journalist turning up in a constituency for a few hours for some vox popping. (The Guardian‘s piece about Chesham and Amersham that managed to omit any references to people voting Lib Dem just a few weeks before Sarah Green’s victory is a classic of the genre, though in really skilled hands, such vox popping can be illuminating, just as a day of spot canvassing around a constituency by a skilled canvasser can be.)
JL Partners pollster James Johnson helpfully dug into the details of the poll beyond what the Sunday Times wrote-up in a Twitter thread. He concluded:
The main hesitations about voting Conservative: trust, Boris, and a sense the Tories are out of touch & only care about the rich. All signs are that partygate has crystallised historic concerns about the Tories and turned the people of Wakefield decidedly against them.
Boris Johnson being an electoral liability matches the continuing finding in national polls that large majorities want him to resign and the net negative ratings for the government overall.
Elsewhere in polling, this week’s national voting intention polls continued the picture of the Conservatives in the low 30s, bumping around the Jeremy Corbyn Labour Party’s level of support in 2019 (33%), Labour consistently ahead but only rarely in the 40s, the Lib Dems up into double figures such that a 10% score is now a disappointment rather than a cause for celebration, and neither the Greens nor Reform prospering from the struggles of Labour and the Conservatives.
Other polling told us that:
- Playing with bringing back imperial measures may have been a big government announcement, but only 11% of the public think it is a “very important” issue. So even though 47% support shops selling goods with imperial measures, the risk is that the policy makes the government look out of touch.
- The big windfall tax and energy bills package has also not moved the polls so far for the government, even though being on an issue that the public does see as important. That may in part be because the windfall tax element is expected by people to increase energy prices (53% increase / 3% reduce) – making it perhaps a less popular measure than it would have been at other times.
- Scottish Labour leader Anas Sawar has the best net ratings in Scotland, beating even Nicola Sturgeon. Lib Dem Alex Cole-Hamilton came in third behind them, as his ratings have risen and those of the Green Party’s leaders have fallen.
- The Queen has a higher approval rating in the Republic of Ireland than any Irish politician who was polled.
