Wes Streeting has made his first major speech as Defence Secretary. Speaking at a defence summit at the Farnborough International Air Show, he said he wants to bring the same approach he used as health secretary — cutting waste and getting better value for money — to the Ministry of Defence. The official transcript was published on gov.uk on 22 July 2026 (UK Government).

Streeting told the summit that as health secretary he had run a "bold programme of reform and modernisation" to make the most of public money and cut waste. He said those reforms had reduced waiting times for hospital treatment in England and delivered millions more appointments. The BBC notes that hospital waiting lists in England did fall to their lowest level in nearly three years in February, backing up Streeting's account (BBC News).

Streeting put it this way: "Modernisation without investment is impractical, but investment without modernisation is irresponsible." In other words, you cannot fix things by spending alone, and you cannot fix them by changing how things work alone — you need both. He said he would follow the same approach in his new job, aiming to make the UK "fit to face the future," a strong ally, and "an engine of growth and jobs here at home" (BBC News).

The timing is awkward. The BBC reports that Labour MP Al Carns quit as a defence minister during a row over funding. Carns later told The Guardian that there was "unbelievable" waste and inefficiency at the Ministry of Defence. He said layers of bureaucracy "cost us more than the product you're getting itself" (BBC News; The Guardian).

Streeting's career path makes this approach consistent. The official list of what ministers do, published on gov.uk on 18 May 2026, says he is responsible for "driving private sector investment in infrastructure and value for money on large national infrastructure projects." A March 2025 version of the same document listed him with responsibilities for "driving efficiency and value for money" and "public sector pay and pensions" (UK Government). A pattern of chasing efficiency and value for money runs through several jobs across two government departments. Streeting is now trying to apply it to defence spending and military equipment.

The money involved is large. The Associated Press reported, in an article by Jill Lawless updated on 30 June 2026, that the UK boosted military spending by $20 billion (Associated Press via AOL). Streeting's argument is that spending more will not deliver what the country needs unless the department also changes how it works.

He had signalled his concern before taking the job. On 12 June 2026, Streeting posted on his Instagram account about "the failure to make the right choices on the Defence" (Instagram).

One complication is that defence affects the whole UK differently. Defence is reserved to Westminster — meaning it is decided by the UK Parliament in London, not by the separate governments in Scotland, Wales and Northern Ireland. But Streeting's talk of defence as "an engine of growth and jobs here at home" reaches into areas like industrial strategy and regional economic development, where those separate governments have their own priorities and their own money to spend.

When Streeting spoke to an NHS conference in November 2025, he focused on high-quality care, value for money, and moving care closer to communities — what he called "the left shift" (UK Government). The defence equivalent of that idea is less clear. What is clear is that Streeting wants to be known not just for spending more on defence, but for making the Ministry of Defence spend it differently.

The broader question is whether this approach will actually work. The Carns resignation, and the strong language Carns used about what he found at the department, will put extra pressure on Streeting to show real results. A secretary of state who built a reputation on efficiency in health has now staked that reputation on doing the same in a department where a departing minister described the waste as "unbelievable." The gap between those two positions is where this story will unfold.
