Ed Miliband has been moved from Energy Secretary to Foreign Secretary in Andy Burnham's cabinet, a reshuffle that follows months of internal briefing against a minister whose flagship net-zero policies made him both the most praised and most attacked figure in Labour's government.

Net zero means cutting greenhouse gas emissions as close to zero as possible, balancing any remaining emissions with measures that remove carbon from the atmosphere. Miliband's policies on this front drew both admiration and hostility.

The Guardian reported on 21 July 2026 that Labour party figures had been briefing against Miliband, with analysts questioning whether his success and public popularity on net zero prompted the attacks. Ed Matthew, UK director at the E3G thinktank, described Miliband as "the most successful minister under the Starmer administration" — a verdict grounded in record levels of renewables contracts and reforms that massively accelerated deployment during Miliband's tenure at the Department for Energy Security and Net Zero from 2024 to 2026 (The Guardian).

Miliband's policy footprint is substantial. He drove the manifesto commitment to ban new oil and gas licences and set a target to decarbonise the UK's power sector by 2030. He previously called the Rosebank oilfield "climate vandalism." In April 2026, he delivered a speech titled "The era of clean energy security" at the Good Growth Foundation's National Growth Debate, and Carbon Brief reported that same month that he planned to double down on net-zero policies with measures to combat an Iran energy shock. On 15 March 2026, his department announced the government would go "further and faster" in becoming energy secure (The Guardian; Gov.uk; Carbon Brief).

That profile made him a magnet for hostile press. Rightwing media publications ran frequent editorials labelling him a "net-zero zealot." Carbon Brief reported that attacks on Miliband in UK newspaper editorials had already exceeded 2024 levels by mid-2026 — a striking volume of sustained editorial hostility toward a single cabinet minister (The Guardian; Carbon Brief).

The pressure intensified as the political context shifted. Andy Burnham succeeded Keir Starmer as Prime Minister before July 2026, and media reports suggested Burnham was preparing to announce new North Sea drilling shortly after taking office. The fossil fuel industry, the Conservatives, Reform UK, and sections of the Labour party itself lobbied Burnham to approve the Jackdaw gasfield and Rosebank oilfield. This created a direct collision with Miliband's record: the manifesto ban on new oil and gas licences contained a loophole for licences already within the planning system, meaning approving Jackdaw or Rosebank would not technically breach it — but doing so would contradict the spirit of the policy Miliband championed (The Guardian).

The environmental backdrop sharpened the contradiction. Three intense heatwaves struck the UK in summer 2026, with firefighters battling wildfires across the country — a visceral reminder of the climate consequences that Miliband's policies were designed to address (The Guardian).

Meanwhile, a parallel briefing war had erupted over the chancellorship. On 22 June 2026, The Guardian reported that advocates for Wes Streeting and those close to Miliband were locked in a fight over who should become chancellor under Burnham. Miliband appeared on Sky News with Sophy Ridge and stated that the Prime Minister would sack whoever had briefed against Streeting. On 20 July 2026, The Guardian reported that John Healey was ultimately appointed chancellor after intense briefing from allies of Miliband, Shabana Mahmood, and Rachel Reeves. Reuters had reported on 16 July that sterling rose and investors expressed relief that Miliband was not chosen as chancellor — Reuters identified the choice as Shabana Mahmood, which the later Guardian reporting updated to Healey (The Guardian; Sky News; The Guardian; Reuters).

Burnham himself vowed to end the briefing wars, The Guardian reported on 19 July 2026, acknowledging that Miliband had been the target of vicious briefing by those who feared his influence. Miliband had helped propel Burnham to the Labour leadership, giving him considerable standing in the new administration. His public profile was further amplified by a podcast co-hosted with radio presenter Geoff Lloyd (The Guardian; The Guardian).

The broader context is one of contrasting fortunes within Starmer's government. The Treasury struggled with feeble growth and political missteps including the winter fuel payments controversy. The NHS was disrupted by doctors' strikes. Against that backdrop, Miliband's energy and net-zero agenda stood out as a rare zone of substantive policy delivery — which is precisely what made him a lightning rod (The Guardian).

Miliband was appointed Secretary of State for Foreign, Commonwealth and Development Affairs on 20 July 2026, according to the UK government's official ministerial page. His move from Energy to the Foreign Office removes him from direct stewardship of the net-zero agenda he built — at the very moment when Burnham's government appears poised to approve new North Sea drilling that Miliband spent his tenure opposing (Gov.uk).

The trajectory bears watching. Miliband's transfer to the Foreign Office could be read as promotion or sidelining, depending on whether Burnham's government intends to maintain the 2030 clean power target. Miliband's long history with the energy brief — he served in the same role under Gordon Brown, photographed at the Little Cheyne Court windfarm in Kent in 2009 — gives the move a particular resonance. The question now is whether his successor at DESNZ will defend the policy architecture Miliband built, or whether the loophole in the manifesto's oil and gas ban becomes the wedge through which it is dismantled.
