Anyone considering a career writing for TV should watch this South Bank Show episode, because Melvyn Bragg’s interviewee is Sally Wainwright.

She’s one of the most successful TV writers of the moment, with credits including Unforgiven, Scott & Bailey, Last Tango in Halifax and Happy Valley.

Sally reveals how she got started, how writing for Coronation Street for five years taught her discipline and how important it is to keep the audience entertained, while at the same time making sure that the drama is firmly grounded in reality.

Warning: watching clips of her shows will make you want to immediately re-watch the whole series!
