How Support for Britain’s Conservative Party is Collapsing

The Conservatives have dominated British politics for 14 years, holding onto power through crisis after crisis, including some of their own making.

Now, as unhappy Britons prepare to go to the polls, the Conservatives are facing the prospect of irrelevance. Polls suggest they could secure their lowest share of seats in Parliament in perhaps a century.

After a turbulent five years of government, their base has fractured.

Some are going left, with the party polling around 20 percentage points behind Labour. Others are heeding the lure of the hard right, with a third of those Britons who voted Conservative last time now saying they will support the anti-immigration Reform party, led by Nigel Farage.

Polls suggest the election results could be catastrophic for the Conservatives. While polling often narrows as an election gets closer, Conservative fortunes have shown little sign of improving.

Here are some key reasons why:

Voters feel the country is worse off

Many voters say they feel the Conservative party has left Britain in a worse state than before it came to power.

Promising to finalize Brexit, which took Britain out of the E.U., was a big vote winner for Conservatives in the last election. Britons have other concerns now. This time, they say, the biggest issues are the economy and health care, followed by immigration. And voters think Labour is better prepared to handle all three, according to polling from YouGov.

Note: Crime and immigration were tied on 22 percent when polled on Dec. 1, 2019, but crime polled as a higher concern on average in the ten polls prior.

Prime Minister Rishi Sunak’s predecessor, Liz Truss, set off an economic crisis after she announced plans for tax cuts, deregulation and borrowing.

Seven and a half million people are waiting for elective care from the National Health Service, five million more than when the Conservatives took power in 2010.

And despite Conservative pledges to reduce immigration, net migration reached an all-time high in 2023.

The loss in confidence in Conservatives to address these issues has followed a period of intense change and turmoil.

The Conservatives oversaw steep spending cuts after the 2009 financial crisis, arguing that austerity would restore public finances. Prime Minister David Cameron called the divisive Brexit referendum in 2016, and then resigned.

Since the last election, the government has had to grapple with Covid-19, an energy crunch after Russia cut gas supplies to Europe, and high inflation. It has also lurched through a series of self-inflicted crises, cycling through three prime ministers and five chancellors, who are responsible for economic policy.

The Conservatives’ most reliable voters are deserting them

Those voters who say they will abandon the Conservatives include some of the party’s most reliable supporters.

Over the last few decades, age has replaced class as the main predictor of political support in Britain, with Conservatives winning more older voters. In the last election, the age at which someone was more likely to vote Conservative than Labour was roughly 40 or older.

Now, polling suggests that Conservatives are only ahead in one age group: people over age 65.

Conservative candidates could be wiped out in Britain’s youngest areas, according to the latest polling from YouGov. And Labour seems poised to make a significant dent among older constituencies too, with the center-left Liberal Democrats eroding Conservative control of seats across the age groups.

In the last election, some of the most deprived areas of the country — based on factors like income, housing and health — voted for the Conservative Party for the first time.

When ballots are counted this time, polls suggest, the party’s supporters may be far less broad-based economically, given how Labour is polling among lower-income people.

At the same time, Keir Starmer, Labour’s leader, has ruthlessly moved the party to the center since taking it over, doing so at the risk of alienating some of the party’s more left-wing supporters. He has made a U-turn on a pledge to spend £28 billion per year on a green investment plan, saying that the country could no longer afford it, and he has been less critical of Israel over civilian deaths in Gaza than many supporters would like.

Polls suggest this approach is costing Labour support among 18- to 24-year-olds as they gravitate to smaller parties, including the Liberal Democrats and the Greens. The seat of Bristol Central — a city with a large amount of young, educated voters in southwest England — could be won by the Green party for the first time.

Losing seats in Labour’s historic heartlands, and beyond

After a disastrous performance in the last election, Labour needs to win an extra 120 seats in Parliament compared to the last election to gain power. It’s an extraordinary number, and a daunting task. Mr. Starmer, the party’s leader, is also unpopular, surveys show, although his standing in polling has improved throughout the campaign.

But the latest polling suggests Labour could win seats across the country and transform Britain’s electoral map.

One key test for Labour will be whether it can win back postindustrial heartlands in the Midlands and north of England, traditionally known as the “red wall.” Many of these seats turned over to Conservative candidates for the first time in 2019 after voters there backed Brexit.

The geography of each party’s voter base is crucial in this election, as Britain’s electoral system rewards parties with highly concentrated voter bases.

The Liberal Democrats are showing particular strength in a small number of wealthier, older seats in England’s south, where it is competing with the Conservative Party for seats rather than Labour. Pollsters expect it to win 30 to 50 seats, almost all at the expense of the Conservatives.

Losing Brexit voters to the far-right

One of the biggest unknowns is how well the hard-right Reform Party will perform.

Nigel Farage, who shook up the campaign in early June when he took over as Reform’s leader, hopes to capitalize on discontent among Conservative voters and rising concern about immigration to win seats in parliament. In the longer term, Farage said he hopes to be a candidate for prime minister by 2029, when the following election would be scheduled.

His gamble appears to be paying off, with a recent YouGov poll finding Reform passing the Conservatives by drawing support from nearly one in five voters surveyed.

“It’s the geography of that support that is so, so dangerous for the Conservatives,” said Will Jennings, a political science professor at the University of Southampton. Unlike the Liberal Democrats, Reform’s voter base is spread thinly across the country, and, while that makes it difficult to win seats, it could split the right-wing vote across the country and cause the Conservatives to lose more seats to Labour.

“Reform picking up 15 to 20 points in some of those constituencies would potentially allow — even if they also pick up a little bit of Labour’s votes as well — Labour to overturn huge majorities,” Mr. Jennings said.
