11:30 James Cartlidge (Conservative)

That this House regrets that the Defence Investment Plan has still not been published despite the Government promising Parliament that the plan would be published in Autumn 2025; notes that the Government’s delay has frozen procurement and has stopped the UK from learning lessons from its long-standing support for Ukraine and left the UK vulnerable as the world becomes more dangerous; believes that the Northern Ireland Troubles Bill and the Northern Ireland Troubles (Legacy and Reconciliation) Act 2023 (Remedial) Order 2025 should not be proceeded with because they are a threat to morale, and that the Diego Garcia Treaty should not be ratified to ensure that the UK continues to have sovereignty over its military base; calls on the Government to publish the Defence Investment Plan as soon as possible; and further calls on the Government to increase spending on the UK’s armed forces, specifically delivering 20,000 more troops over the next Parliament, paid for by restoring the two-child benefit cap, and redirecting net zero funding to defence, to ensure that the UK spends three per cent of GDP on defence by the end of this Parliament.

17:08 James MacCleary (Liberal Democrat)

The defining challenge for our nation is how to meet the unprecedented threat posed by an imperial Kremlin and an unreliable White House. It requires thinking about defence in a new way, because to stand up for values that we cherish, we must be strong enough to defend them. That means, at its core, rearming Britain. Meeting this challenge requires more than military hardware. It means a whole-of-society approach to national resilience. It means energy security, investing in renewables so that we are not dependent on fossil fuels from the very dictators we are standing up to. The Conservatives’ plan to raid investment in renewable energy investment undermines one element of UK security for another—it is robbing Peter to pay Paul. It means food security too. Biodiversity underpins our ability to feed ourselves. Declining ecosystems mean declining food production, and that is a national security risk that we ignore at our peril.

I am proud of this Government for ending the two-child limit, and I am proud of the previous Labour Government who halved child poverty in this country. If Opposition Members truly believed that putting back the two-child limit or ending expenditure on net zero would fund the military, why did they not do it in 14 years? They had 14 years to prepare. In 2022, it was clear where we would get to, and there was nothing from the Opposition side.

“Marine autonomy is a cross-departmental priority of the Government, as detailed in the Maritime Decarbonisation Strategy…the Modern Industrial Strategy…and the Strategic Defence Review…The draft legislation for maritime autonomy exists and the Department for Transport will continue to seek parliamentary time for these important clauses.”
