Centred on the savvy, straight-talking Katherine (Zawe Ashton), who, to her dismay, is reshuffled to her workplace's Northampton outpost, this first TV series from playwright D. C. Moore hovers uncomfortably between comedy and drama for much of its opener. Katherine's new trope-based colleagues - from the non-London bumpkins to her ketamine-addled boss - are as cartoonish as you'd find in any sitcom, yet as an ulterior story about Katherine's previous life slowly surfaces, this transforms into a refreshing and substantial drama.

Chris (Daniel Rigby) is an undercover policeman, currently on a mission to ingratiate himself into a violent Armenian family and gain evidence of their criminal dealings. A mild cop show spoof at times borrowing the mock-dramatic pacing of Charlie Brooker and Daniel Maier's police procedural parody A Touch Of Cloth - but not, sadly, the jokes - what this feels most like is a comedy vehicle for Rigby, otherwise known as the awkward one from the BT adverts. Which would be no bad thing if it weren't such a feeble effort.

The premise goes something like this: each week a celebrity participates in a sort-of immersive theatre production, based around a murder investigation. Teaming up with detective DI Sleet (Tom Davis), the famous person (in this opener, Made in Chelsea's Jamie Laing) meets warped, Stella Street-style versions of celebrities involved in the case, and from these encounters must work out who the culprit is. Possibly the most high-concept show television comedy has ever seen, it's bewildering but occasionally very funny, in a slightly frenzied way.

The irrepressible Alan Carr returns for a 14th series of his charmingly goofy chat show tonight, in which his guests reveal just as much about themselves by the way they react to his Bombay mix and WKD-style of hospitality as from any of the comic's proper questions. On the sofa and partaking in Carr's eccentrically stocked drinks trolley will be The Voice judges - Will.i.am, Ricky Wilson, Tom Jones and the madcap Rita Ora - joined by Antonio Banderas and Danny Dyer. Ella Henderson provides the music.

Caitlin Moran: 'Funniest people in the world are women'

Caitlin Moran and her sister Caz play their childhood for laughs in new sitcom Raised By Wolves. Here the pair talk masturbation, the Midlands and why women have all the best jokes.

Judging by the opener of this 1991-set third series, Chris O'Dowd's generally endearing sitcom seems to be leaning heavily on its retrospective premise for its jokes. As young Martin visits his uncle in Dublin, where he sells encyclopedias with a hefty dose of dramatic irony ("the greatest information resource the world will ever see"), parents Debra and Liam go away to celebrate their anniversary, only to bump into the latter's youth-obsessed old flame. Cue confusion over newfangled things such as yoga and raving.

Carpet salesman and wannabe musician Andy (Nick Helm) has songwriter's block. He also has a restraining order to prevent any contact with his nephew after last series's inadvertent ecstasy consumption. But considering this is a sitcom centred on slacker Andy and nervy nephew Errol's unlikely friendship, this series two opener sees it continue regardless, the 13-year-old secretly visiting his uncle and helping him write one of the comedy musical numbers that usually punctuate the plot.

Sharon receives more worrying news as she's told, thanks to her "geriatric" pregnancy, that her baby has a relatively high chance of being born with Down's syndrome. As she waits for test results, Rob must make amends with Chris's weird wife Fran (Ashley Jensen) after she rumbles the pair's secret bromance. Delaney continues to be likable - if a little one-dimensional - but it's Horgan's anxious, very funny mum-to-be who lends the couple's journey towards parenthood most of its laughs, and all of its emotional weight.

Brooker is back behind his desk, swapping the techno-dystopias of Black Mirror for the equally unsettling current affairs scene. Joining him to strip-search and generally humiliate the week's events will be Cassetteboy and Jake Yapp, along with very confused media commentator Philomena Cunk. And in case you think it'll be a challenge mining laughs from ever-bleaker headlines, Brooker's end-of-2014 Wipe proved that even when the news is gloomy, the way the media breaks it to us will always be ripe for mockery.

Anyone who has been stumped by the acclaim attached to Sharon Horgan - who hasn't really had any sort of hit since her mid-00s sitcom Pulling - should find this new comedy, written with standup Rob Delaney, clears things up. Horgan plays Sharon, a teacher who falls pregnant after a fling with a visiting American (Delaney). With the latter's good guy credentials in serious doubt, Sharon - cynical, scared, angry and all the more likable for it - tentatively starts playing happy families with a man she barely knows.
