After a ten year career holding various roles in national blindness charities, in 2014 Marsha De Cordova entered the world of politics when she became a councillor in Lambeth, south-east London. Last Thursday evening, she unexpectedly won the seat of Battersea from the Conservative minister Jane Ellison with a 10% swing. Born with nystagmus, a condition which makes it difficult for the eyes to focus, she is planning to champion disability rights as she takes her seat in Parliament later this week. We bring you this exclusive interview from Central Lobby in the Palace of Westminster. Presenter: Peter White Producer: Lee Kumutat.
