Great news for fans of Happy Valley - the series shot in Calderdale is set to continue for another two series.

Sally Wainwright, the genius behind the series is keen to continue with the show but wary of 'the rot setting in'.

During a chat with the Daily Star, she explained that she never pens a show with the intention of it airing for just one season.

"I never plan to write one series of anything," the Bafta-winning writer said. You only write one series if it’s not successful, and you don't get recommissioned. But it's when shows get into fifth, sixth, seventh, series that the rot tends to set in."
