Martin Wainwright talks to Lindis Percy

In this series, where journalists follow their personal passions by talking to the people whose stories interest them most, Martin Wainwright interviews persistent campaigners. Having been brought up in a household that was always at action stations as part of his father's long campaign to become a Liberal MP, perseverance has always fascinated Martin. What instils it? What nurtures it? Can it become an obsession at the cost of everything else , including family? In this first programme he talks to Lindis Percy, now approaching seventy, she's been a political campaigner for some forty years, for the last thirty of them on the issue of American airbases in the UK. Lindis has been arrested five hundred times and served fifteen prison terms but she continues to campaign undeterred. Under the banner of the Campaign for the Accountability of American Airbases she still demonstrated every Tuesday outside the base at Menwith Hill in North Yorkshire. Martin joins her there to discover what still inspires her to lobby and litigate when so many of her fellow peace campaigners have fallen by the way side. As a mother of three and a lifelong worker in the National Health Service, how has she managed to juggle her campaigning with family and professional life? Producer: Lucy Lunt.
