Labour Faces Existential Crisis as Wales By-Election Signals Imminent Defeat
A crushing defeat in a Welsh by-election has ignited a firestorm within the Labour Party, with MPs warning that a similar outcome in next May’s local elections could spell the end of Keir Starmer’s leadership. The loss of the Caerphilly Senedd seat to Plaid Cymru underscores a dramatic collapse in Labour’s traditional support base and raises serious questions about the party’s strategic direction.
The result in Caerphilly, a town Labour has controlled for over a century, saw the party secure a mere 11% of the vote – a staggering 27% swing against them. While Plaid Cymru emerged victorious, defeating Reform UK, the scale of Labour’s decline is what has sent shockwaves through Westminster. The outcome fuels fears that Labour could be relegated to third place in Wales, a scenario described by one MP as “unrecoverable” for Starmer.
The by-election loss is particularly alarming given the upcoming elections in May, encompassing over 1,600 council seats across England, as well as parliamentary contests in Wales and Scotland. These elections are widely viewed as a critical juncture for Starmer, with some within his own party predicting a leadership challenge should the results be decisively negative.
Plaid Cymru’s candidate, Lindsay Whittle, secured a resounding victory with 15,961 votes, capturing over 47% of the total. Reform UK’s Llŷr Powell, initially considered the frontrunner, trailed significantly behind, receiving nearly 4,000 fewer votes. Despite the setback, Powell emphasized that the campaign provided valuable lessons for Reform ahead of the broader elections next year, stating that the party is now focused on building a “grassroots campaigning party.”
The Labour collapse, while anticipated by some, has exposed deep-seated vulnerabilities. The party now holds only 29 of the 60 seats in the Senedd, hindering its ability to effectively pass legislation. More fundamentally, many within Labour fear the party lacks a coherent response to the rising challenge posed by both Reform UK and other parties on the left.
Internal dissent is growing. One Labour MP condemned the current strategy emanating from No. 10 as “totally incoherent,” warning that replicating the Caerphilly result nationally in May would be unsustainable. “Everyone’s miserable, everyone’s despondent,” the MP stated. “We can’t just carry on as we are.”
The party’s attempt to unify progressive voters around a “stop Reform” campaign is also facing scrutiny. According to one MP, this strategy relies on Labour remaining the most viable progressive option. “But if people start to think that it’s maybe another party, then suddenly that tactical voting starts to work against Labour and you get punished really badly.” This sentiment is particularly relevant in Wales, where Plaid Cymru is increasingly seen as a credible alternative, as well as in Scotland with the Scottish National Party and potentially the Greens or Liberal Democrats in England.
While Starmer’s impassioned speech at the Labour conference in late September, framing the upcoming elections as a “fight for the soul” of the nation against Reform, initially buoyed some MPs, many feel it lacked substantive follow-up. “People want to hear not just what Labour stands against, but what it stands for,” one MP commented. Another, in a scathing critique, suggested Starmer is being tightly controlled, with recent messaging – delivered by Shabana Mahmood – on immigration deemed “totally incoherent.”
Plaid Cymru’s victory is attributed, in part, to its clear and forceful rejection of Reform UK’s stance on immigration. Party leader Rhun ap Iorwerth declared that the people of Caerphilly had chosen “hope over division and progress over the tired status quo,” positioning Plaid Cymru as “the real choice for Wales.”
Nigel Farage, despite not attending the count, acknowledged the significance of the result, noting the “total collapse of the Labour vote to Plaid.” He characterized the upcoming Senedd elections as a “two-horse race” between Reform UK and Plaid Cymru. This assessment is shared by many within Labour, who are unlikely to be reassured by Downing Street’s downplaying of by-election results as “always difficult for incumbent governments.”
Several MPs believe that a repeat of the Caerphilly outcome in May should serve as a “blaring alarm” for a change in leadership. “We can’t just drift through winter on autopilot,” one senior MP warned. “The loss of Caerphilly is the direct result of the party losing touch with its own voters.” Mainstream, the Andy Burnham-backed centre-left grouping, echoed this sentiment, calling the result “a tragedy, but not a surprise” and criticizing Labour for governing “without a clear vision.”
The criticism extends to Labour’s messaging on key issues. Alun Davies, a Labour Senedd member, publicly criticized his party’s rhetoric on refugees, accusing it of mirroring the language of Reform. However, Cabinet Office minister Nick Thomas-Symonds defended the party’s position, stating that addressing concerns about border security is a “huge priority” for voters.
The situation facing Keir Starmer is increasingly precarious, with the Caerphilly by-election serving as a stark warning of potential electoral disaster. The party’s ability to regain the trust of its core voters and articulate a compelling vision for the future will be crucial in the months ahead.
