Sixteen years after she set up the company while still in her 20s, Red is flying high. Following swiftly on the heels of the BAFTA award-winning Last Tango in Halifax – now in production for a third series – its Sally Wainwright-penned drama Happy Valley proved one of the primetime smashes of the year so far, finishing with almost 8m people in its BBC1 9pm slot.

Other recent hits have included ITV’s Prey and Scott & Bailey, with Russell T Davies’ highly anticipated reunion with Red on Channel 4’s Cucumber and E4’s Banana set to air soon.

Rochdale-born Shindler, 45, had owned 95% but sold a majority stake in the company to Studiocanal in December in a deal thought to value Red at about £30m. Last year she was ranked one of the 100 most powerful women in the UK by Radio 4’s Woman’s Hour.
