Burnham Faces £4.7 Billion Gap to Fund Starmer’s £15 Billion Defence Plan

Q: As Europe rearms, does Britain's £4.7bn defence deficit make it an unreliable ally in the eyes of President Trump?

Probably yes — at least politically, if not militarily. For Donald Trump, alliance reliability is judged heavily through burden-sharing. Britain’s Defence Investment Plan still points to a large overall programme, with £298bn over four years and spending projected to rise from £68.3bn to £79.1bn. The UK is also above NATO’s old 2% benchmark and says it will reach about 2.7% of GDP before the end of the decade, with a longer-term ambition to go higher. On paper, that keeps Britain in the serious-contributor category. The problem is the optics and the timing. A reported £4.7bn funding gap in a plan unveiled during a wider European rearmament drive feeds exactly the argument Trump has often made: that allies announce ambitions faster than they fully fund them. It is especially awkward as NATO members are under pressure to move toward much higher spending goals by 2035, and as other European states are accelerating their increases. That does not automatically make Britain an unreliable ally in operational terms. The UK remains one of NATO’s most capable members, a nuclear power, a major intelligence partner, and a key host for US forces. Those facts matter in Washington. But in Trump’s transactional view, an unfunded gap weakens Britain’s case. If London cannot show a credible route to close the shortfall quickly, the deficit is likely to be seen less as a bookkeeping issue than as evidence that Britain is not fully matching its rhetoric with resources.

A £4.7 billion shortfall remains in the £15 billion defence investment plan that Andy Burnham’s incoming government must cover in the autumn Budget, Defence Minister Luke Pollard said.
Treasury officials have identified only £10.3 billion in savings so far, leaving the next chancellor to allocate budget headroom and find the rest without extra borrowing.
Pollard said Burnham was told about the gap only on Tuesday, a day before the Treasury published the cost breakdown, even as he is widely expected to become prime minister on July 20.
The plan would lift UK defence spending from 2.6% of national income in 2027 to 2.7%—nearly £80 billion—by 2030, with Starmer also claiming a path to 3% in the next parliament and NATO’s 3.5% benchmark by 2035.
To help pay for it, ministers are cutting other departments’ long-term investment budgets by 1%, including £700 million from transport projects and £2 billion from the energy department, with fuller details due in autumn.
