John Healey has been appointed Chancellor of the Exchequer by Prime Minister Andy Burnham, replacing Rachel Reeves in the role. The move comes days after Healey resigned as Defence Secretary on a matter of principle.

Burnham, who took office as Prime Minister on 20 July 2026, chose Healey to return to government immediately, describing the Treasury as "the most vital job of all in cabinet after the prime minister" BBC News.

In his resignation letter as Defence Secretary, Healey wrote that the Treasury had been "unwilling" to "commit the resources that the nation needs to defend the country at this time of rising threats". The Treasury was at that point led by Reeves, the woman Healey is now replacing. BBC News

The pairing of Burnham and Healey at the top of the Treasury carries a clear political logic. BBC sources said the two "have the same outlook" on reindustrialisation, the cost-of-living, and driving growth across the country BBC News. For a Prime Minister whose domestic agenda centres on those three pillars, installing a Chancellor already aligned on substance removes a potential fault line at the heart of government.

Healey's path to the Treasury is unconventional. He served as Secretary of State for Defence from 5 July 2024, when he was appointed as part of the incoming government's ministerial appointments, until 11 June 2026 (Gov.uk; Gov.uk). He was listed as a Secretary of State and cabinet member in the April 2026 edition of the List of Ministers' Interests, published on 9 July 2026 (Gov.uk).

Reeves had held the Chancellorship since 5 July 2024, the same day the government was formed. She was elected as MP for Leeds West and Pudsey in July 2024 (Gov.uk). As of mid-July 2026, Ed Lawrence was listed as Special Adviser to the Chancellor of the Exchequer, serving Reeves (Gov.uk).

Healey was elected as MP for Rawmarsh and Conisbrough in July 2024 (Gov.uk).

The timing layers two events. Healey's resignation from the Ministry of Defence preceded Burnham's by-election in Makerfield. The decision to recall him to the cabinet, this time at No 11 rather than the MoD, followed within days (BBC News).

Healey's clash with Reeves over defence spending, documented in his resignation letter, now acquires an added dimension. The man who accused the Treasury of refusing to fund the nation's defence will run that same department. Whether that translates into a redirected spending review or a revised fiscal framework is a question the first set of spending decisions under the new Chancellor will answer.

The broader context here is the machinery of a fresh premiership taking shape. Burnham has moved quickly to install a trusted ally in the role that controls the public purse, and has done so by promoting someone whose departure from government was, by his own account, driven by the Treasury's own spending decisions. The circle is a neat one, politically: a Chancellor who resigned over fiscal parsimony now positioned to set the fiscal agenda himself.

For Reeves, the sacking brings an abrupt end to a tenure that began on day one of the government. Her special adviser operation, including Lawrence, will transition out with her. No successor spad for the incoming Chancellor has been announced.

For Healey, the appointment returns him to cabinet after little more than a month out of government. His tenure at Defence, just under two years, now gives way to a brief with responsibility for the entire public spending envelope — the very envelope he argued was too tight.
