Today's best TV: Barney Walsh continues his mission to frighten the life out of his dad

BARNEY WALSH continues his mission to frighten the life out of his dad – and Bradley his quest to perpetually embarrass the lad with his dad jokes – throughout Europe, this week touring Italy and taking a trip to picturesque Lake Garda. Bradley gets the perfect vantage point to enjoy the views, when Barney takes him paragliding – providing, of course, Brad can keep his eyes open after the take-off which involves running off the top of Monte Baldo, a nearby mountain. The next day involves a boat trip, but any ideas involving a leisurely cruise about the lake taking in the scenery are quickly banished from Bradley’s mind when he sees the vessel in question – a Formula One speedboat.

Rob Brydon

Would I Lie to You? (BBC1, 8.30pm)

TV’s most consistently entertaining panel show welcomes another tempting line-up of guests, with comedian Sara Pascoe, journalist and presenter Dan Walker, Derry Girls and Bridgerton star Nicola Coughlan, and Derrick Evans, better known as fitness guru Mr Motivator, joining in the fun.

Going undercover

Undercover Police: Hunting Paedophiles (C4, 9pm)

Channel 4 add to their already impressive stable of blue-light reality documentaries with this hard-hitting three-part series, following officers as they adopt undercover online identities in an attempt to lure out people with a sexual or predatory interest in children. It is harrowing work, and as you can expect the documentary doesn’t make for easy viewing, however it is a fascinating insight into the lengths the police go to in order to keep children safe. Unfortunately, there are still plenty of offenders out there who need stopping. In this first shocking edition, an undercover officer pretends to be a 47-year-old paedophile abusing his ten-year-old daughter, looking for other men to join him.

Mary Berry

Celebrity Best Home Cook (BBC1, 9pm)

Proving the TV exec’s adage that if it’s good it can be made better with celebrities is this cookery contest, which as it reaches its halfway point turns its attention to a great British staple – the Sunday roast. Intentionally vague to give the stars free rein to get creative, judge Mary Berry’s only stipulations are that the meal must involve roasted meat and some form of potatoes. This leads to a battle between two of the celebs over who can make the best pork crackling, while another cook opts for a Moroccan theme.

Davina McCall and Nicky Campbell

Meanwhile, Nicki Goscomb and her sisters try to find their brother, who was adopted in 1966.
