North Sea drilling jumps the queue as cabinet splits on Miliband's green line

North Sea drilling jumps the queue as cabinet splits on Miliband's green line Reform UK and wavering Labour ministers are reopening the North Sea question just as Gulf supply shocks keep the bullish case for Brent intact. Reform UK's deputy leader Richard Tice told energy executives that a government led by his poll-leading party would make North Sea drilling a priority, focusing on cutting bills rather than funding green energy, in what Rigzone described on Friday (2026-05-29) as his biggest industry round table to date.⁷ That matters because the political consensus that has governed the basin for a decade is fracturing in public. Several cabinet ministers are privately open to more North Sea drilling and doubt Energy Secretary Ed Miliband's commitment to the green agenda, according to people familiar with the matter cited by Rigzone.⁷ For traders pricing UK upstream exposure, the question of who controls licensing after the next election is no longer a fringe concern. The backdrop is an industry that, on the numbers, is already in retreat. Britain's effective tax rate on oil and gas sits at 78%, among the highest in the world, deterring investment in a basin that already carries high production costs.³ The Economist, writing on Sunday (2026-05-17), called the sector a collapse, arguing Labour's policy is a muddle while dismissing talk of a North Sea renaissance as fanciful.³ The commercial reality on the ground reflects the squeeze. Ithaca Energy completed the purchase of a 50% stake in two Shell licenses in the West of Shetland Basin while agreeing to farm down its interest in the Fotla discovery, Rigzone reported on Friday (2026-05-22).⁴ Majors are reshuffling West of Shetland positions rather than committing fresh capital, and the deal flow tells you which way the basin is leaning. The political fight is loudest over what subsidises what. In a Holyrood debate on Thursday (2026-05-28), the offshore wind sector was described as funded by subsidies paid by 70 million people across the UK through the contracts for difference scheme, with critics challenging the SNP to explain how independence would cut bills by a third without dismantling that support.⁶ The CfD mechanism that built Scottish offshore wind is now a target, and Reform's pitch is explicitly to redirect that money toward bills. Set against the domestic argument is a global price signal that strengthens the case for any barrel the North Sea can still produce. The consensus in this packet leans bullish on Brent crude front-month, with all weighted signals pointing one way.¹ The driver is supply, not demand. European gas told the story first. The ICE Endex TTF front-month closed the fourth quarter at 26.73 EUR/MWh, then climbed from the second week of January to exceed 33 EUR/MWh, a rise of more than 20% before easing in February, Elenger reported in its Q1 overview.¹ That move predated the worst of the supply disruption. Then came the Gulf. Attacks on critical energy infrastructure, most notably the Ras Laffan complex in Qatar that handles around 20% of global LNG supply, intensified the squeeze, according to Elenger.¹ The assessment was that 17% of Qatar's LNG would be out for three to five years following the damage from military strikes.¹ A multi-year cut to a fifth of the world's LNG export capacity is the kind of shock that keeps a bid under crude and gas alike. The Guardian framed the domestic stakes bluntly on Monday (2026-05-18), arguing Britain faces its second energy crisis in four years, worsened by a lack of preparation, with the blockade of the Gulf petroleum artery following the earlier shock of Russia's invasion of Ukraine.² A country importing more of its energy is more exposed to exactly this kind of external supply break. There is a longer arc here that explains why the politics run so hot. North Sea revenues peaked at 3% of GDP in the mid-1980s, the dividend that helped fund the tax cuts at the core of the Thatcher revolution.³ That fiscal cushion is gone, and the argument now is whether to manage decline or attempt to slow it. For the basin itself, the decommissioning debate is already advancing. A University of Aberdeen study, with the National Decommissioning Centre and marine science partners, found that old platforms can support marine ecosystems as artificial reefs, though it called for a case-by-case approach, Energy Voice reported on Monday (2026-05-25).⁵ When the conversation turns to what to do with retired infrastructure, the direction of travel is hard to mistake. The signal to watch is whether wavering cabinet ministers move from private doubt to public dissent on licensing, and whether the Ras Laffan outage estimate holds. A confirmed multi-year loss of 17% of Qatari LNG would harden the bullish Brent case, and a UK government newly willing to license would have a far stronger price backdrop to justify it than it did a quarter ago.^7,1
