Ministers are putting the final touches on the plan, which is expected to be published in the coming weeks after departments agreed to cut their capital budgets by about 1% to pay for additional military spending. Allies say Keir Starmer wants the plan to form part of his legacy should he be replaced as prime minister by the Greater Manchester mayor, Andy Burnham, in the coming weeks. But the months-long dispute between the Ministry of Defence , the Treasury and No 10 has left senior members of the government trading accusations about each other, insiders say. “The whole process has been a mess,” said one Whitehall official. “First the Ministry of Defence told everyone their plans were fully costed and didn’t need extra cash. “They infuriated people by then coming back and asking for billions more, but then the Treasury absolutely refused to budge, dragging this out for much longer than they should have.” Starmer’s spokesperson said on Monday: “The prime minister is determined to get the Dip right to ensure we deliver the best equipment and technology into the hands of our frontline forces, whilst investing in and growing the UK economy.” He agreed last February to increase defence spending to 2.5% of gross domestic product in the belief that it would be enough to fund the promises made in the strategic defence review, which was being worked on at the time. That review was published in June to coincide with the cross-government spending review, which confirmed nearly £20bn extra for the MoD over five years. Within months, however, defence officials said they would need another £28bn over the next four years to pay for the commitments in the defence review. “The MoD conducted a defence review at the same time as the Treasury was doing its spending review specifically to avoid this scenario,” said one government source. Another said: “The MoD has a terrible record in keeping its costs down so it is galling to be asked for more money just months after the defence review.” ‘The potential is huge’: Plymouth hopes defence money will have it sailing again Read more The defence secretary, John Healey, ended up requesting about £18bn from the Treasury, but Rachel Reeves refused to sign off on anything above £12bn for weeks.
