Series one finished with the couple still planning to move abroad, but with Edith’s 50-year-old son Roger (Jason Watkins) showing no signs of leaving home or reuniting with his estranged wife Wendy (Rosie Cavaliero).
Johnston said: “I’m thrilled to be working with such a great cast of actors. Some are new friends and some are old friends – it is a joy to be joining them all.”
John Cleese added: “I really enjoyed making the first series. It was great to be able to do so much sitting-down acting. I look forward to seeing our lovely cast again.”
Written by Charles McKeown the first series performed well, pulling in 6m viewers for the opening episode.
