Current government policy is for the army to shed almost 10,000 posts, reducing its size from a target of 82,000 to just 72,500 troops by 2025 – by far the smallest in hundreds of years. But Ben Wallace warned that without a guarantee of significant new funding, total defense spending is forecast to fall below Nato’s key target of 2% of national income by the second half of the decade. His intervention, in an interview with Sky News, is significant because he has yet to publicly state whether he is backing Liz Truss or Rishi Sunak in the Tory leadership contest. Politics Live: Sunak accused of ‘demanding’ in TV debate – and Truss has her job offer taken back? Asked who he was backing, the senior cabinet minister said: “I’ll see what happens in the discussions. I know them both very, very well…I’m interested in what they say on defence.” Mrs Truss, the foreign secretary, has said she will increase defense spending to 3% of gross domestic product (GDP) by the end of the decade. Mr Sunak, by contrast, has said he is opposed to “arbitrary targets” and, while he has said he sees Nato’s 2% target as “a floor not a ceiling”, the former chancellor said only that British defense spending would rise . to 2.5% “over time”. Wallace made a clear pitch to the two prime ministerial candidates on the need for extra defense funding after the £24 billion spending increase he secured from Boris Johnson over the four years to 2024. “I think defense needs more money because the threat has increased and I’m under my leadership,” he said, speaking on Monday while returning to the UK from a trip to Slovakia.

We’re going down. We’re going from the first (highest defense cost) in Europe to the eighth in Europe and they keep falling.” As for how an increase in defense spending to 3% of GDP by 2030 might affect the size and capabilities of the army, Royal Navy and Royal Air Force, Mr Wallace said some equipment programs would likely be bought faster. He also said the military would carry out a review of the lessons that can be learned from Russia’s invasion of Ukraine into vulnerabilities in the UK’s defense that need fixing. This is to include the requirement for more long-range artillery systems.

Mr Wallace – who may or may not still be in the job in September – stressed that it would be up to army chiefs to set out future force plans.
