The Quantum of Solace actor tweeted: “Such a shame. I have just heard that the BBC will not be making any more Upstairs Downstairs. I loved the show and will miss is greatly.”

Starring Keeley Hawes (Ashes to Ashes) and Alex Kingston (Doctor Who), the revamped Upstairs Downstairs returned for a second series earlier this year and concluded last month.

Update: Writer and executive producer Heidi Thomas has confirmed the news this afternoon on Twitter.

Thomas tweeted: “Truly sad about [Upstairs Downstairs], but can now fully and wholeheartedly honour the massive commitments I have elsewhere, including Call the Midwife.”

She added: “Not surprised – and a bit relieved as my diary was looking unworkable. But I will miss the characters.”
