Lorraine Heggessey, chief executive at London-based Talkback Thames, is leaving the post after five years. A spokesperson for the prodco, which is the UK production arm of FremantleMedia, has confirmed the news to the UK press. Sara Geater, the company’s COO, will act as interim CEO, reporting to Tony Cohen, chief exec of FremantleMedia. Various UK media outlets have speculated that ITV’s axing of the long-running police series The Bill, produced by Talkback Thames, may have influenced Heggessey’s decision to leave. The prodco revealed at the time of the decision that the cancellation would result in job losses. At present, no announcement has been made regarding where Heggessey may be headed to next. Prior to her time at Talkback Thames, she was with the BBC, and was the first female controller for BBC1.
