Martin Lewis is easily one of Britain's most influential and trusted journalists. His Money Saving Expert website ranks as one of the most-read news sites in the UK, his weekly newsletter has around 9 million subscribers, and he is a regular face on prime-time TV. In a wide-ranging interview, Martin joins Ros Atkins to discuss his career in media, the state of British journalism, and the toll being in the public eye has had on his mental health. He also talks about his campaign against scam ads on social media, and singles out Facebook-owner Meta for criticism, who told the BBC in October: "We're constantly working to improve our systems and encourage anyone who sees content they believe breaks our rules to report it using our in-app tools so we can investigate and take action."Producer: Dan Hardoon Presenter: Ros Atkins
