Is Britain Actually Broke?: Healey rules out three big tax risesBackground
John Healey has served as Chancellor of the Exchequer since July 2026. Andy Burnham appointed him during the Cabinet formed between 20 and 23 July, after Rachel Reeves left government.
Before the Treasury, Healey was Defence Secretary from 2024 until June 2026. His record there included the rapid procurement of the Skyhammer interceptor from Cambridge Aerospace in April 2026 and the launch of finance routes for defence startups without prior government contracts.
He also oversaw Britain's early military response to the 2026 Iran conflict. In May, he named Typhoons, HMS Dragon, mine-clearance vessels and drones as the British contribution to a Hormuz coalition. That mix of defence procurement, Coalition planning and fiscal policy defines the two main parts of his ministerial career.
Healey narrows his Budget options
On 7 September 2026, Healey promised not to raise income tax or corporation tax, and kept value added tax off the table too. On 28 September, he pledged to meet the fiscal rules at the 28 October Budget. Those commitments left him with smaller taxes, spending choices, thresholds and welfare as the main remaining levers.
By 21 October 2026, welfare spending was reported about £2.5bn above expectations for September. That overshoot sharpened the trade-off created by Healey's own tax pledges: benefits were both a source of pressure and one of the few large policy areas still open to change.
Healey opened defence finance to newcomers
On 22 April 2026, Healey and then-Chancellor Rachel Reeves made the Defence Investors' Advisory Group permanent. They launched Sprint, designed to co-invest private capital alongside Ministry of Defence contracts, and Zig-Zag, which brought private-sector finance staff into the department. Both routes targeted defence startups without prior government contracts.
By 13 May 2026, the National Wealth Fund had made its first direct defence investment before either new mechanism had deployed capital. That contrast showed both the direction of Healey's Reform and its early execution gap: he had opened routes for newcomers, but another public fund moved first.
Healey named Britain's coalition force
On 22 April 2026, the Ministry of Defence hosted 30 nations at Northwood to plan mine clearance in the strait of Hormuz while Healey was Defence Secretary.
On 12 May 2026, Healey co-chaired the Coalition's planning meeting with France's defence minister. The next day he named Britain's contribution: Typhoon fighters, HMS Dragon, mine-clearance vessels and reconnaissance drones. Naming real platforms turned his diplomatic role into a military commitment, although deployment still depended on a Ceasefire and agreed rules for the mission.
