UK needs wartime defence spending in face of most dangerous time since Cold War, ex-civil service chief warns

Britain must ramp up its defence and aid spending and bolster its diplomatic and intelligence networks amid “the most dangerous period” since the Cold War, the UK’s former top civil servant has warned.

Writing in The Independent, former cabinet secretary Sir Mark Sedwill urged the government to nearly double Britain’s defence spending to reach 4 per cent of GDP and restore the international aid budget to 0.7 per cent of national income, slashed by Boris Johnson in 2021.
