The new series is now here. Series 2 guide

Last Tango In Halifax was a huge, huge hit in 2012 - over 7 million viewers tuned into the comedy drama and it went on to win awards including a BAFTA.

Now (July 2013) filming has started on the hotly anticipated second series. Derek Jacobi and Anne Reid are reprising the roles of love struck septuagenarians Alan and Celia, who rediscover their love for each other later 60 years after they first met.

It's also confirmed that Sarah Lancashire, Nicola Walker, Tony Gardner, Dean Andrews, Nina Sosanya and Ronni Ancona are on set to take part in the new six-part series.

Series 2 is currently filming in various locations around the north of England. It picks up the dramatic storyline that had viewers on the edge of their seats last year... With Alan having suffered a serious heart attack and the couples' nuptials hanging in the balance, viewers were left wondering whether Celia will once again lose the love of her life.

Meanwhile, Celia's successful and uncompromising daughter Caroline is forced to face up to her newly discovered sexuality, the demands of her girlfriend Kate, her mother's prejudice and a failed marriage. While Alan's daughter Gillian, both independent and insecure, finds herself in a surprising love triangle having cheated on her partner Robbie with Caroline's hapless husband John.

Writer 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."

Executive Producer Nicola Shindler adds: "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 2 promises even more ups and downs putting even the strongest bonds to the test."
