Content: Starmer challenged over defence investment plan delay. 33 minutes ago. Paul SeddonPolitical reporter. Getty Image. Sir Keir Starmer has failed to say when the government’s military funding plan will be published, amid an escalating row over UK defence spending.. The prime minister is facing growing pressure to set out when the much-delayed blueprint will appear, as talks with the Treasury continue.. It comes after the Labour peer who carried out a review of defence capability last year launched a scathing public attack on the hold-up.. Former defence secretary and Nato chief Lord Robertson accused the government of “corrosive complacency” amid rising threats around the world.. Former Nato chief warns UK’s national security ‘in peril’. UK facing £28bn defence spending gap claims. Ministers have not denied reports that the Ministry of Defence (MoD) has requested billions in further funding to buy equipment following an internal assessment by officials at the department last year..

In reply, Badenoch accused the prime minister of “prosecuting past governments” rather than reassuring defence companies of “what he is going to do”.. In a subsequent statement in Parliament, Defence Minister Luke Pollard insisted the government was “not waiting” on the investment plan to announce further defence projects, but was “working flat out to” get the document published.. But he faced pressure from Labour MP Tan Dhesi, who chairs the defence select committee, who warned that further delay to the plan risked “further damage to our defence-industrial base”.. The MoD’s budget is due to rise by 3.6% in real terms by 2029, under departmental spending plans fixed last year.. The investment plan is meant to replace decade-long “equipment plans” released on a rolling yearly basis until 2022, when the then-Conservative government halted publication whilst it assessed the effect of “extraordinary inflati
