The romantic drama stars Derek Jacobi and Anne Reid as a couple reunited after 60 years and was a ratings hit when it aired last year, attracting audiences of more than 7m.
Produced by Red Productions, the show also stars Sarah Lancashire, Nicola Walker, Tony Gardner and Dean Andrews who all return for the second series.
Producers say the new episodes pick up the dramatic storyline that had viewers on the edge of their seats last year. With Alan (Jacobi) having suffered a serious heart attack and the couples’ nuptials hanging in the balance, viewers were left wondering whether Celia (Reid) will once again lose the love of her life.
Meanwhile, Celia’s successful and uncompromising daughter Caroline (Lancashire) is forced to face up to her newly discovered sexuality, the demands of her girlfriend Kate (Sosanya), her mother’s prejudice and a failed marriage.
While Alan’s daughter Gillian (Walker), both independent and insecure, finds herself in a surprising love triangle having cheated on her partner Robbie (Andrews) with Caroline’s hapless husband John (Gardner).
Sally Wainwright says: “The inspiration for Last Tango in Halifax was deeply personal so I am delighted that it also resonated with so many viewers – both young and old.
“The second series will bring even more dramatic twists, trials and tribulations for the characters with Alan and Celia’s love story continuing to be the beating heart of the series.”
Nicola Shindler, Executive Producer and founder of Red Production Company, said; “When we started developing Last Tango in Halifax we wanted to make a love story first and foremost.
“The audience instantly warmed to the simple and sincere affection between Alan and Celia, which endured despite the dramatic events that transpired around them. Series two promises even more ups and downs putting even the strongest bonds to the test.”
