Burnham's First Week: Britain's Sovereignty vs. Balance Sheet

Andy Burnham spent his first week trying to prove that a change of prime minister could still change the direction of Britain. He moved part of the machinery of government to Manchester, called his administration a “circuit breaker” and promised to put the cost of living ahead of Westminster ritual. By Sunday he was also promising to disagree publicly with Donald Trump when British interests required it, ruling out UK participation in offensive US operations against Iran while preserving support for Ukraine.

The difficulty is that every one of those promises carries a bill. Britain’s budget watchdog says debt interest reached £111.2 billion in the financial year to April, 8.3% of government spending. Burnham also inherited a £4.7 billion gap in the defence investment plan, according to the Institute for Fiscal Studies, before finding money for energy relief, housing and public services. Former Goldman Sachs chief economist Jim O’Neill, who has advised Burnham, reduced the challenge to two words: “get real.” The new government’s political energy is genuine; its fiscal headroom is not.

John Healey’s appointment as chancellor captures the tension. Healey resigned as defence secretary because Keir Starmer would not fund the armed forces at the level he considered necessary, yet he now has to police the Treasury while finding that money himself. Newcastle University political scientist Martin Farr argued that the choice neutralised two immediate vulnerabilities—defence and market confidence—without resolving either. Burnham declined to promise 3% of GDP for defence by 2030, even as Defence Secretary Wes Streeting inherited a force with acute submarine-readiness problems and BAE Systems chief Charles Woodburn warned that Britain had become complacent about the risk of attack.

Iran supplied the first external test. The IRGC declared RAF Fairford a legitimate target after US B-1 bombers used the British base in the Iran campaign. Two US EA-37B Compass Call electronic-warfare aircraft arrived there as the threat was issued. Streeting said Britain was ready to defend itself and dismissed Tehran’s language as sabre-rattling, but the episode exposed the narrow line Burnham is drawing: refusing to join offensive strikes while hosting American assets central to the campaign. A Russian frigate’s live-fire drill roughly 40 nautical miles south of Plymouth, shadowed by HMS Tyne and a French aircraft, made strategic distance harder to maintain.

The Iran war was already entering British kitchens and mortgages. Average two-year fixed mortgage rates rose to 5.59% and five-year rates to 5.61% as lenders’ funding costs increased; more than 100 products were temporarily withdrawn. In Northern Ireland, the average cost of 500 litres of heating oil climbed £98.78 in three weeks to £445.37, a 29% increase in a region where about two-thirds of households use the fuel. The Bank of England has held Bank Rate at 3.75%, but economists at Deutsche Bank, Nomura and Capital Economics warned that oil sustained around $90–$100 could force rate increases rather than cuts. The Bank’s own April scenario treated the energy shock as a direct cost increase for an economy that imports energy.

Burnham also paused the early-release provisions of the Sentencing Act after victims’ families protested, while Greater Manchester Police admitted that officers had failed to examine phones seized from Jihad Al-Shamie before his 2025 attack on Heaton Park Synagogue. Those decisions reinforced the new prime minister’s instinct to move quickly and visibly. They also added prisons, policing and victim protection to the same competition for money.

The first week succeeded as politics: Labour regained attention, Burnham spoke plainly and No. 10 North gave devolution a physical address. The harder test arrives with the first budget and the next Bank of England decision. Britain can refuse an American war, promise a stronger military and shield households from its energy costs, but it cannot do all three through tone alone.
