Westminster’s corridors are crackling with fury as Reform UK’s policy chief Zia Yusuf dropped a political thermite bomb on Chancellor Rachel Reeves, branding her a serial deceiver whose career is “built on deceit” in a scorching GB News interview that has Labour scrambling for cover. “She’s been lying her whole career!” Yusuf thundered, his voice laced with contempt, just hours before Reform leader Nigel Farage fired off a bombshell 968-word letter to Prime Minister Sir Keir Starmer’s independent ethics adviser, demanding an urgent probe into Reeves’ alleged ministerial code breaches over the Autumn Budget’s fiscal fiasco.

The accusation? That Reeves peddled a “sustained and deliberate narrative” of a £22-40 billion “black hole” in public finances to justify brutal tax hikes, while secretly knowing the Office for Budget Responsibility (OBR) had greenlit billions in headroom. As the firestorm erupts—complete with leaked Treasury briefings and Starmer’s inner circle in meltdown—opposition benches are howling for blood, with Farage vowing: “This isn’t spin; it’s sleaze on a Shakespearean scale.” In a Commons gripped by chaos, this could be the spark that ignites Labour’s first major rebellion since taking power.

The tinderbox lit on November 30, 2025, when Yusuf—Reform’s sharp-suited strategist and Farage’s right-hand firebrand—sat down with GB News’ Dawn Neesom for what started as a chat on BBC bias but veered into a full-frontal assault. Yusuf didn’t mince words, tracing Reeves’ “deceit” from her Bank of England days as an economist (“fudging forecasts to climb the greasy pole”) to her shadow chancellor tenure (“hyping a non-existent crisis to weaponize fear”), culminating in the Budget’s “treachery.” “From the doorstep of No. 11, she’s lied about the black hole, about her CV, about everything,” Yusuf seethed, slamming her for not disclosing the OBR’s positive fiscal outlook during heated November Commons clashes. “If she gets away with this, we’re plumbing new depths in British politics—deeper than the Mariana Trench.” He accused her of a “conscious choice” to hike taxes on working families while shielding “extortionate” spending on foreign aid and migrants, echoing Reform’s pre-Budget blueprint to slash £25 billion by axing EU benefits and doubling NHS surcharges. Hours later, Farage escalated, penning his missive to Sir Laurie Magnus, the PM’s ethics tsar, citing Reeves’ “inaccurate statements” on her professional background (a nod to past rows over her Goldman Sachs tenure) and her “misrepresentation” that saddled voters with “the heaviest tax burden in generations.” “This meets the threshold for formal investigation—advise Starmer now,” Farage demanded, dragging the PM into the fray by alleging he knew of the Treasury’s “pre-Budget briefing strategy.”

Reeves, 46, the first female chancellor and Labour’s economic wunderkind, hit back with icy defiance on Channel 4 News: “These are desperate smears from a party obsessed with division. The black hole was real—£22 billion verified—and my Budget fixes it without austerity’s scars.” But cracks are showing: leaked memos reveal OBR officials flagged “positive headroom” pre-Budget, yet Reeves pressed on with £40 billion in levies, from employer NI hikes to frozen thresholds. Labour insiders whisper of a “civil war” brewing—frontbenchers like Angela Rayner privately fuming over the optics, while backbench rebels eye a no-confidence push if Magnus greenlights the probe. “Keir’s confronting his top team in Cabinet,” one source spilled to GB News. “Leaks are flying; trust is shattered.”

The timing couldn’t be crueler for Starmer, whose “mission-driven” government is reeling from donor scandals and migration U-turns. Reform, polling at 18% and nipping at Tory heels, smells blood: Yusuf’s broadside ties into their narrative of a “Westminster elite” gaslighting the public, amplified by Farage’s X megaphone (2.5 million followers) posting the letter with #ReevesLies. Social media is ablaze—#BudgetBetrayal trends with 500k posts, memes of Reeves as Pinocchio flooding timelines, and punters at 3/1 odds on a probe launch by Christmas. “Yusuf’s nailed her—deceit from day one,” cheered @ReformRiser (10k likes), while Labour loyalists counter: “Farage’s deflection from his Russian ties?”—a jab at recent LBC grillings where Yusuf bristled at questions on Farage as a “Russian asset” amid Kremlin bribe convictions in Reform’s Welsh wing.

Tories, led by Kemi Badenoch, are piling on: “Reeves’ fibs make Truss look transparent—probe her now!” Even Lib Dems’ Ed Davey called for “full disclosure.” As Magnus mulls his response—expected imminently—this accusation isn’t just rocking Westminster; it’s fracturing Labour’s veneer of competence. Yusuf, the Oxford-educated firebrand who’s morphed Reform from Brexit splinter to populist powerhouse, warned: “The British people are sick of being taken for fools.” With the Budget’s tax sting still fresh—hitting pensions, savings, and salaries—Farage’s ethics salvo could topple Reeves, or worse, Starmer’s slim majority. In the bear pit of PMQs tomorrow, expect fireworks: deceit, probes, and a chancellor on the ropes. The political firestorm? It’s not erupting—it’s inferno.
