A Decade of Leadership Changes

In the past ten years, the UK has seen six prime ministers, none of whom departed on their own terms. When asked by Professor Sir John Curtice if British politics has become unmanageable, he offers a nuanced perspective. He suggests that while there may be patterns, each resignation has its unique context. For instance, David Cameron resigned in 2016 following the Brexit referendum loss, while Theresa May stepped down in 2019 due to her inability to secure a Brexit agreement in Parliament. Curtice argues that Boris Johnson's resignation in 2022 was less about Brexit and more about Conservative MPs losing faith in his integrity. Liz Truss's fiscal policies unsettled the markets, and Rishi Sunak's resignation was not voluntary but rather a consequence of the election he lost. According to Curtice, Brexit is a significant factor in only "two and a half out of six" resignations.

However, a deeper issue has been brewing for decades. Curtice notes that Members of Parliament (MPs) have become increasingly assertive and less inclined to adhere to party lines, a trend that began during the immigration debates under Edward Heath in the early 1970s. While Cameron was ousted by a referendum and Sunak by voters, Johnson and Truss faced backlash from their own party members, and May was undermined by internal divisions. Curtice identifies this growing assertiveness among MPs as a common thread that complicates the ability of any prime minister to maintain confidence in the Commons.

This assertiveness has also impacted Keir Starmer. Curtice is candid in stating that the anticipated landslide victory in 2024 was not as solid as it appeared. He attributes the overwhelming majority to the electoral system rather than genuine electoral support, noting that Labour secured only 35% of the vote, marking the lowest share for a majority government in UK history. The Reform party siphoned off a significant portion of the Conservative vote, leading to Labour winning nearly a hundred additional seats through tactical voting, despite a decline in its own vote in many areas. This outcome has been described as a "loveless victory," as voters were more eager to oust the Conservatives than to embrace Labour.

Starmer's leadership challenges further highlight these issues. Curtice points out that Starmer has struggled to articulate a clear narrative for his government, and even he has acknowledged that his party lacks confidence in his ability to lead them past Reform in the next election.

The Rise of Andy Burnham

Is Andy Burnham the Future Prime Minister?

As the political landscape shifts, attention turns to Andy Burnham. Curtice expresses confidence that Burnham is a strong contender for the next prime minister. Following Burnham's impressive performance, Labour MPs are optimistic that he can effectively challenge Reform and safeguard their parliamentary positions, as many fear losing their seats to this emerging party. They view Burnham as a more compelling communicator and a more popular figure compared to Starmer.

However, Curtice warns that transitioning from a successful mayor of Greater Manchester to the complexities of Downing Street is a significant leap, requiring the formulation of policies that stimulate growth and improve the health service. He does not foresee any surprise candidates emerging, stating firmly, "No, no, no. It's Mr. Burnham." Wes Streeting, a potential rival, has aligned himself with Burnham, leading Curtice to predict a lack of real competition and suggests that a new Prime Minister could be in place by July 17th.

The Influence of Nigel Farage and Reform

Nigel Farage's Ongoing Impact

The shadow of Nigel Farage looms large over the current political climate. For over a year, one party has consistently led the polls, and it is neither Labour nor the Conservatives. Curtice observes that none of the major parties enjoy genuine popularity; Reform, despite sitting at only 27%, holds a seven-point lead, making it challenging to prevent Farage from potentially becoming Prime Minister. However, he quickly adds that the next election is still three years away, and many developments could alter the landscape. If Reform is to decline, it would likely be due to a Conservative recovery, especially with Kemi Badenoch gaining some popularity after a recent by-election win. Meanwhile, Labour has been losing votes to the Greens more than to Reform, a nuance that some Labour MPs have yet to recognize.

Is this a uniquely British phenomenon? Curtice broadens the discussion for an international audience, noting that across Western Europe, established parties have faced significant upheaval since 1989. In contrast, Britain has remained relatively stable. However, he argues that Brexit has disrupted much of this stability, contributing to the current fragmentation. Curtice refrains from making predictions, acknowledging that Farage could still emerge victorious, and both Labour and the Conservatives might recover. He concludes that the future of British politics remains uncertain, presenting a substantial challenge for both major parties.
