Rachel Reeves, the Chancellor, faced accusations of turning Britain into an 'economic laughing stock' after a sudden U-turn on plans to raise income tax. After weeks of laying the groundwork for a potential manifesto-breaking tax hike for millions of workers in the upcoming Budget, she sparked chaos in the City by performing a shock reversal on Friday.

Government sources indicated that this change of heart stemmed from improved forecasts from the Office for Budget Responsibility (OBR), which presented a £20 billion financial gap to fill—significantly less than initially feared. However, critics, including Labour MPs, suggested the dramatic move was made due to fears of losing seats if the pre-election pledge not to increase taxes on workers was broken, especially following botched No 10 briefings about a possible coup against Keir Starmer.

While Treasury sources downplayed suggestions of changing income tax thresholds, it is widely expected that current bandings will be frozen for several more years, potentially pulling millions into higher tax brackets. Instead of a single income tax increase, the Chancellor will now need to identify other revenue streams to bridge the financial gap, potentially leading to a "smorgasbord" of other rises. These could include pay-per-mile charges for electric car drivers, higher gambling taxes, and cuts to tax relief for workers utilizing 'salary sacrifice' schemes for expensive bicycles.

Shadow Chancellor Mel Stride heavily criticized the situation, stating, 'We are witnessing the most shambolic pre-Budget period in memory. The constant leaking, briefing and kite-flying is fuelling uncertainty and damaging our economy. Markets are unnerved and business confidence is at a record low. This is chaos on an industrial scale. We are becoming an economic laughing stock under Labour.' Former chancellor Sir Jeremy Hunt echoed this sentiment, noting, 'The whole world is reading this information and they’re looking at British economic decision-making. And it looks very chaotic and I don’t think that’s a good thing.'

The build-up to the U-turn involved several weeks of hints and speculation. Earlier this month, Ms Reeves was seen with her diary displaying the word 'Thresholds' related to a meeting. She gave an unexpected 'scene-setter' speech in Downing Street where she failed to rule out tax hikes and later told the BBC that sticking to manifesto commitments would require 'deep cuts in capital spending.' It was understood she had informed the OBR of plans to raise the basic rate of income tax by 2p, offset by a 2p cut in employee National Insurance, aiming to raise £6 billion. However, the Financial Times revealed on Thursday night that she had 'ripped up' this proposal, leading to a sell-off in gilts and soaring government borrowing costs.

Nigel Green, CEO of deVere Group, warned of 'credibility shocks' and 'mixed signals' from the Treasury. Anna Leach of the Institute of Directors highlighted the 'deeply damaging' impact on business confidence. Even Labour’s preferred think-tank, the Resolution Foundation, noted that 'excessive levels of Budget kite-flying risk exacerbating market uncertainty,' with its chief executive Ruth Curtice stating, 'It is not normal for so much of that to be laid bare in public.'

The U-turn was reportedly influenced by an internal Labour party revolt, with MPs fearing that breaking the manifesto promise on tax would be 'electoral suicide.' Health Secretary Wes Streeting welcomed the decision, emphasizing the importance of not breaking manifesto pledges to rebuild trust in politics. Labour’s new Deputy Leader Lucy Powell and former minister Catherine West also publicly opposed breaking promises, drawing comparisons to the Liberal Democrats' collapse after backtracking on tuition fees.

Critics accused the government's economic policy of being driven by Left-wing backbenchers, who previously forced Ms Reeves to abandon a £5 billion cut to disability benefits. Economist Lord O’Neill suggested the change in mindset was due to divisions within the Labour Party, warning against prioritizing 'party consolidation ahead of fiscal credibility' and resorting to 'tinkering at the edges' that could damage growth. Reform UK Deputy Leader Richard Tice criticized the 'Budget shambles' and the government's focus on backbench whims rather than the British people, noting rebelling bond markets and furious voters.

The market chaos was not solely due to the U-turn. The FTSE 100 took a £27 billion hit, closing 1.1% lower, caught in a global sell-off. This began on Wall Street due to concerns about US interest rates and an AI 'bubble' in tech stocks, particularly chip maker Nvidia. The initial slump was followed by falls in Asian markets, with London's slump being the most pronounced, wiping £27 billion off the value of the UK’s 100 biggest listed firms. Heavyweight financial firms like NatWest and Barclays were severely impacted, alongside gambling sector firms like Entain and Evoke, which are now seen as potential targets for alternative tax raids.

Historically, Chancellors maintained strict secrecy around the Budget to prevent market damage and public panic, with past figures like Hugh Dalton even resigning over leaks. This secrecy aimed to prevent 'every kind of stunt' and ensure economic stability. The current 'pitch-rolling' approach, where theoretical policies are floated, has been criticized for having 'human consequences,' such as anxious savers rushing to take pension lump sums early after aides leaked consideration of reducing the tax-free sum. This particular leak was deemed 'callous and cruel' as savers cannot reverse their decisions. Critics ultimately portray the Chancellor as 'weak, rudderless and devoid of any coherent vision for reviving the economy,' predicting that hard-pressed families will suffer most from the 'omnishambles Budget.'
