Surely You're Joking...

The saga began in December 2003, when Tony Blair’s transport secretary Alistair Darling published a White Paper declaring that a third runway was an urgent national necessity that would be operational by roughly 2015. Gordon Brown rubber-stamped it again in 2009. Ed Miliband was Energy Secretary back then too, and alongside Hilary Benn, he grumbled in Cabinet while the whips pushed it through anyway. Then the theatrical oscillation began. David Cameron arrived promising "no ifs, no buts, no third runway," and immediately scrapped it in 2010 to placate leafy west London Tory seats and the Lib Dems. Boris Johnson famously pledged to lay down in front of the bulldozers to stop it. But because Whitehall cannot actually make a permanent decision, Cameron merely outsourced the cowardice by setting up the Howard Davies Airports Commission in 2012 to spend three years and £20 million concluding what the government had already announced a decade earlier: build the runway at Heathrow. By 2018, Theresa May’s government pushed through the Airports National Policy Statement (NPS) with a massive cross-party majority. Boris Johnson conveniently found an urgent diplomatic mission to Afghanistan so he wouldn't have to vote, let alone meet a bulldozer. That is where both legacy parties engineered their own legal catastrophe. Under the 2008 Climate Change Act—passed by Miliband himself—and the subsequent 2015 Paris Agreement commitments, the British state bound its own executive authority into rigid, legally enforceable statutory carbon budgets. Yet when Chris Grayling drafted the NPS in 2018, the Department for Transport simply ignored the Paris targets in the text. The result was an inevitable legal bloodbath. In February 2020, the Court of Appeal ruled the government’s approval illegal precisely because ministers had neglected their own statutory international climate duties. Even though the Supreme Court reversed that specific block in late 2020—ruling Heathrow Airport Ltd could technically seek a Development Consent Order—the legal and planning architecture was permanently poisoned. Both parties spent two decades creating a hyper-regulated planning apparatus that gives local councils, judicial review activists, and environmental litigation charities total veto power over national infrastructure. Fast-forward to today, and the absurdity has simply come full circle. Rachel Reeves and the Treasury want the £49 billion private infrastructure capital to generate a fraction of a percent of GDP growth to rescue their fiscal rules. Meanwhile, Ed Miliband sits across the table holding the statutory Net Zero mandate, fully aware that allocating aviation emissions to an expanded Heathrow blows up his legally binding carbon budgets elsewhere. What happens next is entirely predictable: The Cabinet will manufacture a compromised statement about "supporting expansion in principle provided it meets strict environmental and noise tests". Heathrow Airport Ltd will spend another half-decade preparing a 50,000-page Development Consent Order. The Mayor of London, Hillingdon, Wandsworth, and Greenpeace will instantly tie it up in High Court judicial reviews until at least 2029. The projected opening date, already quietly pushed back towards 2039, will slip into the 2040s. Britain cannot pour concrete over the M25 because the managerial state has designed a system where legal process, regulatory vetoes, and Cabinet buck-passing are valued infinitely higher than national capability.
