What’s on telly tonight? Our pick of the best shows on Wednesday 26th September

Silk Road Adventure, 9pm, ITV

The remarkable and diverse country of Iran is Joanna Lumley’s latest port of call as she continues to trace the iconic silk trading route. As well as trying to get a feel for modern life in the enigmatic nation, she also examines its history, stretching back to the powerful Persian Empire, and recalls the time her grandparents visited the country in the 1920s. Along with the striking ruined city of Persepolis and the Golestan Palace, she explores one of Iran’s glorious paradise gardens and, in the city of Isfahan, visits the vibrant Naqsh-e Jahan – the biggest enclosed square in the world. She also examines the importance of faith when she takes a trip to a gym that practises a centuries-old mixture of sport and religion. Rating: ****

Bad Move, 8pm, ITV

As the sitcom continues, it seems things are looking up for put-upon Steve (Jack Dee), who’s hoping to land a big contract for his web design business. A meeting with potential client Imelda, a successful interior designer, goes well – but when Steve tries to impress her by bragging about the amazing renovation job that he and wife Nicky (Kerry Godliman) have done to their idyllic country cottage, his lie backfires when Imelda says she wants to see it. The chances of landing the contract now seem slim – especially as Nicky’s just discovered the drain smell in the house is being caused by a septic tank that’s ‘backing up’. Eugh! Rating: ***

Alex, 11.05pm, C4

On the outside, Alex Leko is a devoted father and policeman. But behind the façade, he is a drug-fuelled dirty cop who has made a deal with the devil – local crime boss BG. This new six-part Swedish thriller opens with Alex accidentally killing his partner and best friend, and deciding he’s going to go straight. So he lets BG know that his days of being on the take are over. Obviously, BG doesn’t take the news well and makes it clear that Alex isn’t going to walk away from his operation that easily. As well as battling to free himself from BG, Alex also has a new partner, by-the-book cop Frida Kanto, who is secretly working to find enough dirt on him to have him prosecuted. Rating: ****

More previews tomorrow.
