The UK Treasury, under Chancellor Rachel Reeves, has directed ministers to stop non-priority spending as part of its upcoming spending review through 2029. Reeves aims for efficiency savings of 5% across department budgets, which will be independently reviewed by expert panels. Critics, including Conservatives and Liberal Democrats, have challenged Reeves’ approach, cautioning against cuts to social care. The Treasury emphasizes accountability, insisting all expenditures must contribute to the government’s priorities, as outlined in Prime Minister Sir Keir Starmer’s recent Plan for Change.
