Starmer’s delayed defence plan was published with a £4.7 billion funding gap, after months of uncertainty that suppliers said slowed contracts, delayed investment and pushed production decisions overseas.
Britain’s nine-month delay in publishing its Defence Investment Plan strained the domestic defence supply chain, with companies saying Ministry of Defence contracting slowed, investment was deferred and some smaller firms failed or exited defence activity. Prime Minister Keir Starmer unveiled the long-delayed plan on Tuesday, pledging an extra £15 billion to make the armed forces war-ready, but accompanying documents showed a £4.7 billion gap, or about a third of the funding, still needs to be identified in a budget later this year. Industry executives said the earlier lack of clarity had already reduced investor confidence and shifted manufacturing and commercial focus toward faster-growing overseas markets including Germany, Poland, the Nordics, the Baltics, Canada and the United States. The Institute for Fiscal Studies said closing the shortfall could require deeper spending cuts, higher taxes or more borrowing, while critics also noted the plan does not specify when defence spending will reach 3% of GDP on the way to Britain’s NATO commitment of 3.5% by 2035.
