The Salisbury Poisonings: A Spy Next Door, airing at 9pm on Sky Documentaries, uses first-hand testimony to recount the 2018 poisoning of former Russian spy Sergei Skripal and his daughter Yulia. Journalist Emma Volney recalls her first week in local radio that year: "I said to myself: 'Don't worry, nothing happens in Salisbury.' You don't expect to see two people on a bench foaming at the mouth." The documentary also features former prime minister Theresa May, intelligence officials, and counterterrorism leaders.
