Defection Wave: From Tory Centre to Liberal Bench
Cody Butler, a 21‑year‑old who once chaired the One Nation Conservative Network, stood on the platform of the Brighton Centre clutching a Liberal Britain tote bag. His presence at the Liberal Democrats’ annual gathering was a visible sign of a broader migration. In July he resigned his Tory role, citing a party that no longer welcomed centrists, Remainers and those concerned about the climate crisis. “It feels like finding a new family,” he said, reflecting on the abrupt shift from being a “local Tory boy” to a newcomer in a rival camp. Butler is not alone. Josh Bancroft, a 26‑year‑old former councillor on Cannock Chase, left the Conservatives earlier this month, echoing similar sentiments about being “forced out of the big tent”. Both men are now helping to launch a fresh grouping, the One Nation Liberals, aimed at attracting other disillusioned Tories who see the Lib Dems as a viable home.
The Push Factors: Badenoch’s Purge and Climate Stance
The exodus coincides with a series of moves by Kemi Badenoch, the Conservative leader, that have alienated moderate members. In July she warned that support for net‑zero targets or adherence to the European Convention on Human Rights would bar individuals from standing as Tory candidates. The warnings were swiftly followed by the removal of the whip from former minister Gavin Barwell and the blocking of another ex‑cabinet minister, Grant Shapps, from seeking re‑election. “The Conservatives have taken leaps to the right and left me and millions of voters behind,” Bancroft observed. The perceived purge has accelerated a trend of centrist voters reassessing their allegiance, with many concluding that the Lib Dems now better reflect their priorities on climate action and human rights.

Building a New Faction: One Nation Liberals Take Shape
The nascent One Nation Liberals aim to provide a structured outlet for disaffected Tories. Butler and Bancroft have already begun recruiting, hoping to capitalise on a growing pool of Conservatives who feel squeezed out by the party’s rightward trajectory. “My politics haven’t changed, but the party has,” Bancroft said, underscoring a common narrative of ideological drift. The group’s emergence reflects a strategic effort to consolidate moderate talent ahead of future elections, positioning the Lib Dems not just as a third party but as a potential kingmaker in a fragmented political landscape. The party’s leader, Ed Davey, has repeatedly highlighted Badenoch’s policies as a catalyst for this shift, framing the Lib Dems as the natural home for those who value evidence‑based climate policy and a centrist approach to governance.
Davey’s Ambitions: From Third Party to Potential Kingmaker
Despite languishing at around 11 % in national polls, Liberal Democrat activists in Brighton exuded confidence about expanding their parliamentary presence. The party already holds 72 seats, its largest share in over a century, and finished second in 27 constituencies in 2024, 20 of which were previously Tory strongholds. “There is no ceiling to our ambitions,” Davey declared, insisting that strong local candidates and campaigners could defeat any opponent in multi‑party contests. He explicitly ruled out a future pact with the Conservatives, but left the door open to negotiations with Labour, arguing that maximising Lib Dem MPs would strengthen his party’s bargaining power. “We have to box really smartly,” he warned, suggesting that the party’s growing clout could reshape coalition dynamics.

Why it Matters
The defections of Butler, Bancroft and their peers signal a seismic realignment in British politics, as the Conservative Party’s drift toward the right pulls a generation of moderates into the Liberal Democrat fold. This migration not only bolsters the Lib Dems’ numbers but also injects fresh credibility into their claim of being the true custodians of centrist, climate‑focused governance. If the One Nation Liberals gain traction, they could become the decisive bloc in any post‑election negotiations, effectively rewriting the rules of power‑sharing in Westminster. The implications extend beyond party politics: a revitalised Lib Dem contingent could force both major parties to recalibrate their positions on net‑zero, human rights and other pivotal issues, reshaping the national agenda for years to come.
