Rishi Sunak is under pressure to boost defence spending after two serving ministers publicly called for a “much greater pace” of investment.
The call from Foreign Office minister Anne-Marie Trevelyan and security minister Tom Tugendhat came after the Budget was criticised for failing to boost defence spending.
The two senior Tories said the UK needs to “lead the way” by increasing defence and security spending to at least 2.5% of gross domestic product (GDP), a measure of the size of the economy.
“The sad truth is that the world is no longer benign,” they said.
“Protecting ourselves requires investment. And effective investment means that our industrial complex must grow and strengthen at much greater pace than at present.
“We cannot turn on the complex platforms and weapons which ensure military advantage overnight. We must start that growth now, invest at pace to support our allies and stay ahead of our adversaries.”
The article by Ms Trevelyan and Mr Tugendhat was not required to be cleared by No 10 because it is a social media post and it is also in line with Government policy on increasing spending to 2.5%.
However, it is a very visible sign of unease within the Tory ranks about the state of the defence budget.
The Commons’ spending watchdog warned on Friday that the Ministry of Defence has no credible plan to fund the armed forces the Government wants, leaving the UK increasingly forced to rely on its allies.
The gap between the MoD’s budget and the cost of the UK’s desired military capabilities has ballooned to £16.9 billion, its largest deficit ever, despite an injection of £46.3 billion over the next 10 years, the watchdog said.
But the influential Public Accounts Committee (PAC) warned that the real deficit could be closer to £29 billion as some parts of the armed forces only included capabilities that were affordable rather than all those the Government had requested.”
Ms Trevelyan, the Indo-Pacific minister, and Mr Tugendhat were both concerned about the level of defence spending needed to respond to China’s increasingly assertive global role.
“Russia is committed to spending 40% of its expenditure on defence and security this year. Vast sums by any standard to fight its illegal war in Ukraine,” they said.
“By contrast, the US defence budget is 842 billion dollars this year, up less than 50% over the same period. And the UK’s defence budget has risen from £43 billion to £55 billion – an increase of only 28%.”
They added: “It’s clear to us that the UK needs to lead the way in increasing our own domestic defence and security spending commitments to 2.5% and beyond.
“Former defence secretary Ben Wallace and prime minister Boris Johnson made inroads into growing our defence budgets, which had been shrinking in real terms for years, but that only filled the hole. Now we need growth.”
In a Sunday Times interview, Mr Sunak defended his record on funding the military.
“I would just point to our record here as chancellor when I oversaw the largest increase in the defence budget since the end of the Cold War with a £24 billion uplift,” he said.
“The whole point is, we recognised that the world that we’re living in was becoming more dangerous, and we had to invest more to protect the country against that.”
