Stuart Anderson MP has urged the government to ensure that government expenditure on defence "meets our needs and prepares us for war, should it arise."
It comes as Britain's most senior military chief warns that the Ministry of Defence is preparing to make huge cuts to our Armed Forces as a result of being short of £28 billion over the next four years.
The Conservative Party has published a fully costed plan to boost the UK's defence industry by £50 billion.
Under plans revealed by the Conservative Party, billions of pounds would be redirected from vanity Net Zero projects to a £50 billion Sovereign Defence Fund.
It follows an earlier intervention in November, where Stuart pointed out that an equivalent to half of the spending on the UK's defence budget is being spent on expensive Net Zero subsidies.
Britain has fallen down official NATO defence spending rankings and is now the 12th biggest defence spender as a share of gross domestic product (GDP).
Stuart has endorsed the Conservative Party's Plan, which he has said would accelerate war readiness and send a powerful message to adversaries like China.
The investment would also enable the procurement of new drone technologies at a far greater pace and scale - transforming the lethality of the British Armed Forces.
The Fund would repurpose £11 billion from the National Wealth Fund - which is currently largely allocated to clean energy schemes - by rebranding it as the National Defence and Resilience Bank.
It would mobilise billions in public and private investment by taking stakes in UK defence start-ups, investing in dual-use companies, and supporting the resilience of supply chains.
In Parliament, Stuart Anderson MP asked:
"The world is rearming and rebuilding the defence industrial base at a rapid pace, and it is fair to say that the UK is starting to fall behind some of our NATO allies. Does the Secretary of State believe that the spending planned for 2027 to 2030 and onwards meets our needs and prepares us for war, should it arise?"
In response, Defence Secretary John Healey said:
"I do indeed. The hon. Gentleman knows as much about defence as anyone else in this House, and I pay tribute to him for his work on the NATO Parliamentary Assembly delegation. The commitment this Government made in our first year to increasing defence spending by the largest sustained amounts since the end of the cold war is an historic move. Our commitment, alongside NATO allies, to increase to 5% of GDP what we put towards national security is part of strengthening the NATO deterrent and NATO defence; and our strategic defence review allows us to map out a way of making our forces more ready to fight and better able to deter."
Stuart anticipated calls from NATO by asking the Government to commit 3.5% of GDP to defence spending and 1.5% of defence-related spending.
Despite announcing plans to increase overall defence spending, the government has still refused to commit to raising it to this level. This is despite a rising NATO expenditure target. Labour has also axed £500 million of defence projects without any clear plan to replace them.
Stuart has said that this failure risks leaving our Armed Forces wihout the equipment or capabilities needed to defend our country.
