This week's Must Listen is Last Man Standing.
Last Man Standing is a podcast that tells the story of John Cantlie - a British journalist who was captured by Islamic State in Syria and remained captive.
The episode description reads 'In 2012, British photojournalist John Cantlie was kidnapped in Syria by Islamic State. While his fellow hostages were released or murdered, he remained captive. Then, a series of Isis propaganda videos emerged, fronted by Cantlie. He hasn’t been seen since. In this new series, the Times’ war correspondent Anthony Loyd sets out to investigate the life - and fate - of the missing hostage.'
