Britain should show allies like the US a willingness to “get our hands dirty” on defence commitments and undertake “the biggest peacetime programme of rearmament in our country’s history”, Kemi Badenoch has said.The Tory leader said the UK should not “miss the underlying lesson” in US President Donald Trump’s complaints that Europe must invest more in its own security.Speaking at the London Defence Conference, Mrs Badenoch conceded she had found the US President’s public lambasting of Prime Minister Sir Keir Starmer “disconcerting.”
