Debate

Defence Investment Plan

Contribution

I am grateful to Mr Speaker for granting this urgent question. Before I begin, may I pay tribute to the three Royal Navy personnel who tragically died in a helicopter crash last week? We offer our heartfelt condolences to their families from this side of the House. After months of delay, there has been considerable speculation that the defence investment plan will finally be delivered this week. Is that the case? Specifically, and to echo what Mr Speaker just said, there has been considerable speculation that the DIP may be published on Friday. As Mr Speaker said, this House is not sitting on Friday. Let us be clear: with a war on two fronts, this is not just another Government publication, but, given the context, a vital moment for our country and for this Parliament. Does the Minister understand that it would be totally unacceptable to all Members if the defence investment plan was published on a day when the House is not sitting? Can he explicitly confirm, when he gets up, that the defence investment plan will be published when the House is sitting? You need no reminding, Madam Deputy Speaker, of the total shambles in this Chamber last June when Labour published its strategic defence review and gave advance sight of that market sensitive document to the defence industry from 8 am that morning, while I, as shadow Defence Secretary, never got to see a copy before responding from this Dispatch Box. So will the Minister also give an absolute assurance that, whenever the DIP is published, first sight—before the document is shared with any other external stakeholders—will be reserved for Members of this House? There is a reason the DIP has been delayed so long, which is that Labour still has not worked out how to pay for it, but former Labour Defence Secretary George Robertson and former Labour Prime Minister Tony Blair both know the answer: the Government should cut welfare to fund defence. If the Minister disagrees and believes the welfare budget should not be touched to fund defence, will he at least tell us whether the defence investment plan will set out a fully funded path to 3% of GDP, and, crucially, whether the Treasury has signed off the defence investment plan yet? Last week the Secretary of State said at Defence oral questions that “the Prime Minister is determined that we publish the defence investment plan before the NATO summit.”—[Official Report, 1 June 2026; Vol. 786, c. 840.] That begs the question: which NATO summit and which Prime Minister?
