Sources reveal Treasury chief Rachel Reeves is preparing a sovereign wealth fund pivot as new Defence Secretary Dan Jarvis reviews the £13.5bn offer that triggered John Healey’s exit.
Behind the locked gates of the G7 summit in France tonight, a very different conversation is taking place. While the world focuses on the dramatic exit of John Healey—who told journalists he resigned because the Treasury was “unwilling” to find the cash—Sir Keir Starmer has effectively frozen Britain’s traditional defence budget.
A senior Whitehall source told this newspaper that the Prime Minister has instructed the Ministry of Defence to stop asking for extra "running cash." Instead, he is betting the house on a radical, unannounced financial weapon: a hybrid sovereign wealth fund designed to borrow against future peace dividends.
The Real Reason for the Blockade-Contrary to reports that the Treasury has simply run out of money—offering only £13.5bn to plug an £18bn gap—the truth is more strategic. Chancellor Rachel Reeves has drawn a line in the sand. She has told allies she will not repeat the "fiscal error" of the Ukraine emergency spending spree, which poured billions into ammunition stockpiles with no long-term growth return. She wants defence to pay for itself.
Sources confirm that the £13.5bn figure was never meant to be the final settlement. It was a "trap door" designed to force the MoD to accept a new fiscal model: the Defence, Security and Resilience Bank (DSRB).
This is the information not yet published. Britain has secretly re-engaged in the DSRB negotiations in Montreal—after previously sending only an attaché as an observer . The plan, backed by international partners, is to create an AAA-rated lending institution that would allow the UK to borrow for tanks and drones without it appearing on the current deficit spreadsheet.
Jarvis’s Secret Plan- Dan Jarvis, the former paratrooper who replaced Healey, has reportedly accepted the premise that the era of unlimited Treasury handouts is over. However, he has issued an ultimatum to the Prime Minister: he needs a "transition bridge."
What happens next is critical. Jarvis is using the next two weeks to demand that the Treasury increase the immediate cash offer from £13.5bn to £18bn . This is not for new jets, but to keep the army "in the field" while the DSRB legal charter is finalized.
“They can’t sack him or let him resign,” an ally of the new Defence Secretary told The Guardian this weekend . “Dan will need something to come away with from the Nato summit in Ankara, there is no question” .
The 2030 Reckoning-The political genius—and the danger—of Starmer’s strategy lies in the timeline. He has conceded to Nato Secretary General Mark Rutte that the UK will hit 3% of GDP by the end of the next parliament (2034) , but he refuses to legislate for 2030 .
By punting the major spending hikes past the next general election, Starmer is betting that the DSRB will be operational by 2028, flooding the MoD with private capital. If it fails, the British Army faces a "hollowing out" worse than the 2010 strategic defence review, with a projected spend of just 2.68% of GDP in 2030—a figure Healey described as "making the country less safe" .
What No One is Saying-The most sensitive detail, which No 10 is refusing to brief, is the impact on welfare and domestic capital.
While the headline is "No more money for defence," the reality is that every other department is being raided. Culture Secretary Lisa Nandy confirmed this weekend that discussions are happening in “real time” to force other ministries to hand over their capital budgets . The Treasury is imposing a 1% cut on capital projects across Whitehall.
But even that isn’t enough. A highly placed source in the investment banking sector told this newspaper that the Treasury is preparing to raid the NHS capital budget for the third time in two years—a move that will likely trigger a fresh confrontation with health unions by August.
Starmer is not being "weak" on defence, as his opponents claim. He is playing a long fiscal game. By refusing Healey the cash, he is forcing the military to accept a Wall Street-style financing model that has never been tried on this scale for sovereign defence.
If Jarvis pulls this off, Britain will have found a way to rearm without raising taxes. If he fails, the resignation of John Healey will look like a prelude to a national security crisis.
