PORRIDGE, BBC1, FRIDAY 9.30PM

In this sequel to the classic 1970s sitcom, Kevin Bishop (with Harry Peacock and Ricky Grover) is Nigel Fletcher, the hapless grandson of Ronnie Barker’s laconic jailbird, Fletch.

He’s a chip off the old block and is doing a stretch in Wakeley Prison after a series of botched cybercrimes when falls foul of the spiteful warden Officer Meekie, but help of sorts is at hand.
