Burnham's Chancellor Must Find £4.7bn for Starmer's £15bn 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.

£4.7bn still has to be found in the autumn Budget to fund Sir Keir Starmer's £15bn defence investment plan, defence minister Luke Pollard said, leaving the task to Burnham's incoming chancellor.
Only £10.3bn in savings has been identified for the four-year package, and Pollard said Burnham was told about the shortfall on Tuesday as the Treasury published the cost breakdown.
Dan Jarvis said the government had ended uncertainty by publishing the plan but would now need talks with the next prime minister to secure enough money to meet the armed forces commitments.
Defence spending is set to rise from 2.6% of national income in 2027 to 2.7%—nearly £80bn—by 2030, funded partly by 1% cuts to other departments rather than extra borrowing.
Those offsets already include £700m from transport and £2bn from energy budgets, with possible road-project cancellations triggering backlash from local Labour leaders and MPs.
