A set of promotional images for the new season of Last Tango in Halifax have been released, featuring new cast member Rupert Graves (Sherlock).

Starring Derek Jacobi and Anne Reid as love-struck septuagenarians Alan and Celia, the comedy-drama’s third season begins on BBC One later this month, with Graves joining the cast as Gary, “a handsome man from Halifax”.

Sarah Lancashire (Happy Valley) and Nicola Walker (Spooks) are also back as Caroline and Gillian.

Season 3’s opening episode begins with a Valentine’s Day date between Gillian and Gary. But as the evening draws on, things aren’t quite what they seem.

Meanwhile, Alan and Celia discuss going on a honeymoon adventure to New Zealand to visit Alan’s brother Ted, but their happiness is short-lived however when someone turns up from Alan’s past with devastating consequences.
