NEW SITCOM

Warren, 9pm, BBC1

MARTIN CLUNES (pictured) plays a rude and selfish driving instructor who is also incredibly tight-fisted, to the extent that he still has dial-up internet. It takes a lot to make such an unhappy and unappealing character watchable — his partner adores him, but we’re not given a reason to, at least not yet — so you can see why they chose Clunes for the role.
