“We need more voices on telly – there’s not enough working-class people in telly and not enough diversity,” said UKTV head of comedy entertainment Iain Coyle.

“All the different voices that make up this country need to be working in television – not just the poshos who’ve been to Cambridge and Oxford,” said Sohail Shah, the MD of new indie King of Sunshine Productions.

He added: “Without new talent you don’t get any kind of progression in TV.”

The three-part series, entitled Comedy Against Living Miserably, aims to raise awareness and money for the mental health charity with comics waiving their fee as a donation to the charity.

The series builds upon Dave’s relationship with CALM since last year’s “Be the Mate You’d Want” campaign, where they encouraged viewers to spend the ad time calling or texting a friend.

To commemorate 50 years since the first broadcast of classic sitcom Dad’s Army, the three episodes lost from the BBC archive have been recreated for Gold.

The new episodes, written by David Croft and Jimmy Perry, continue from the original sitcom as bank manager-turned-squad leader Captain Mainwaring (Kevin R. McNally) takes command of a local group of Home Guards during the Second World War.

Greg Davies and Alex Horne will return to their golden thrones as they continue to test the competency of famous faces with an array of complex and comedic tasks.

This series will see comedians Jo Brand, David Baddiel, Ed Gamble, Rose Matafeo and actor Katy Wix battle it out for the title of Taskmaster champion.

Sex on Trial

Monday: Channel 4, 10.00pm

Sex on Trial examines high-profile student sexual assault cases in the US and explores the impact they have had on the people making the accusations and the accused.

Timewasters has charmed critics and attracted healthy audiences with its mix of jazz, time travel and good jokes. Notably, it also has an all-black leading cast but, according to its creator, Daniel Lawrence Taylor, it is, “first and foremost”, a comedy.

Greg Davies and Alex Horne return to judge a new batch of famous competitors and will decide who is worthy of taking home the coveted 24-carat gold cast of Greg Davies’s face.

The new contestants include Love Island narrator Iain Stirling, actor Joe Thomas (White Gold), stand-up comic Lou Sanders, Paul Sinha (The Chase) and RTS award-winner Sian Gibson. 

Each episode will see a different chef recreating their most treasured recipes. The series will also feature pictures and stories from the chef’s personal archives to illustrate each dish’s life-changing impact.

Other chefs to be appear include Monica Galetti, Michel Roux Jr, Giorgio Locatelli, Rosemary Shrager, Michael Caines, Daniel Clifford and Ollie Dabbous.

“This series provides a real insight into the recipe for success behind some of our most-loved chefs,” said Good Food channel director, Vicky Walker.

They will be joined by stand-up Lou Sanders, Paul Sinha (The Chase) and Sian Gibson (Car Share), all set to bravely face the challenges set by Taskmaster Greg Davies.

Creator and stats keeper Alex Horne will also be returning to the game show, which was originally performed at the Edinburgh Fringe.

Previous contestants include Jessica Knappett (Drifters), James Acaster (Would I Lie to You?) and Rhod Gilbert (8 out of 10 Cats Does Countdown).
