Rory Stewart caused a buzz when he challenged Boris Johnson for leadership of the Conservative Party. He did not win the leadership, but he won widespread support for his ‘Rory Walks’ campaign across the United Kingdom, from Brits of all political stripes. He is also known for his walks across Afghanistan, where he was hunted by the Taliban in the mountains between Herat and Kabul at the height of the United States occupation in 2001. Stewart has been a diplomat, a politician, a soldier and - some say - a spy. But you’ll find him today championing one of his biggest passions - international aid, as the head of GiveDirectly, one of the biggest international charities in the world. One Decision’s Julia Macfarlane and Sir Richard Dearlove talk with Stewart and discuss whether the United Kingdom’s handling of its aid and soft power has seen better days, and what it means for Britain’s place in the world.
