Joining Renkow, who stars as Tim, a man who uses his cerebral palsy to get away with saying and doing just about anything, are James Norton (Happy Valley), Lee Ridley (Christmas Comedy Club With Lost Voice Guy), Sally Phillips (Bridget Jones's Diary), Lydia Fleming (In from the Cold) and Gary Beadle (Andor).
Happy Valley last aired in 2016, and speaking to Radio Times earlier this year, Sally Wainwright confirmed that the new series will jump time accordingly, taking place seven years after the events of the last.
In one image, Sarah Lancashire can be seen making her final outing as Sergeant Catherine Cawood, sporting a bloody nose after a police raid.
After a five-year hiatus, Wainwright has written six new episodes of the West Yorkshire set police drama, with Sarah Lancashire returning to her iconic role as Sergeant Catherine Cawood.
James Norton (McMafia) will reprise his role as Tommy Lee Royce, the murderer and sex-offender who assaulted Catherine’s daughter. Siobhan Finneran (Alma’s Not Normal) will also return as Catherine’s sister, the recovering addict Clare Cartwright.
Based on the notorious Profumo Affair in the 1960s, the series follows young model Christine Keeler (Sophie Cookson) who has an affair with politician John Profumo (Ben Miles)
Keeler is simultaneously accused of being involved with a Soviet naval officer and is, as a result, placed at the centre of a possible national security risk.
Also joining the cast is Ellie Bamber (The Nutcracker and the Four Realms), Nathan Stewart-Jarrett (Misfits) and Anthony Welsh (Black Mirror).
With his family living in exile in London, Alex Goodman - played by James Norton (Happy Valley, War and Peace) - is forced to confront all values that he holds dear.
He is the English-raised son of Russian exiles with a mafia history, and as a result has spent his life trying to escape the shadows of that criminal past, creating his own business and enjoying life with his girlfriend.
What starts out as a tale of survival becomes a murderous story of his constant struggle against the lures of corruption in the modern world.
