Andy Burnham became Prime Minister on 21 July 2026 and held his first cabinet meeting at 10 Downing Street that same day. His Chancellor of the Exchequer — the government's top finance minister — is John Healey MP. The pair's first announcement was a cut to the tax on household electricity bills, which they said would "give breathing space" on the cost of living. GOV.UK

Healey's appointment was confirmed on 20 July, the day Burnham took office. Reuters The New York Times reported the same day on Burnham putting his cabinet together as he succeeded Keir Starmer. The New York Times Burnham is the seventh person to serve as Prime Minister in the past ten years. CNBC

The first cabinet meeting on 21 July gathered senior ministers at Downing Street for the usual photocall and their first round of coordination. Reuters Connect The BBC put out a video the same day titled "Who is the UK's new chancellor?", reflecting an effort to introduce Healey to the wider public. BBC The BBC's coverage listed Healey as a related topic on that page.

The electricity-bill tax cut was the main policy of the first day. The government's press release, attributed to both Healey and Burnham, described it as a step to ease household energy costs. GOV.UK

On foreign policy, Burnham spoke by phone with NATO Secretary General Mark Rutte on 20 July. GOV.UK No details of what was discussed have been published, but the government confirmed the call took place. The conversation, on Burnham's first day in office, followed a long-standing tradition of new prime ministers reaching out to key allies early.

The broader context here is worth noting. Seven prime ministers in ten years means rapid turnover at the top, with each one arriving with a plan and leaving before voters had a chance to judge that plan at a general election. Choosing a tax cut on electricity bills as the first announcement sends a clear signal: the new government's immediate priority is the cost of living, not cutting government borrowing or changing how institutions work. Whether that priority holds will become clearer at the Autumn Budget and the spending review that follows.

Energy policy also involves the UK's devolved governments — the separate administrations in Scotland, Wales and Northern Ireland that run many local services. The rules around electricity are set by Westminster, but how support reaches households is partly managed by those devolved governments, especially in Scotland and Northern Ireland. A UK-wide tax cut will reach households in all four nations, but the practical details will play out differently in Holyrood (the Scottish Parliament), the Senedd (the Welsh Parliament) and Stormont (the Northern Ireland Assembly).

Healey's move to the Treasury is worth watching for another reason. His background is in defence and local government, not economics. Fellow MPs will be paying close attention to how he handles his first questioning session in Parliament and how financial markets respond to his early signals.

The first 24 hours of the Burnham government set out three things: the Chancellor is Healey; the first domestic policy is an electricity-tax cut; and the Prime Minister has made early contact with NATO's leadership. What comes next will emerge in the coming weeks as the cabinet settles in and Parliament gets to work.
