Here are the picks of tonight's TV...

Hairy Bikers: Route 66 (BBC2, 8pm)

THE fact Dave and Si have not made a show about the legendary Route 66 before now is remarkable, and aside from mouthwatering cooking sketches, there will also be a large portion of American history to digest. The first leg sees them travelling from Chicago to St Louis. In the windy city, we see how migrant workers were drawn into its meatpacking industry, and with them came a line-up of dishes as diverse as the region’s population. Later they receive an invitation from the Amish community, where they cook together and learn more about this very different way of life. Crossing the Mississippi into Missouri, Dave and Si visit the city of St Louis, where they sample concrete custard.

Watchdog Live (BBC1, 8pm)

MATT Allwright, Steph McGovern and Nikki Fox return with the consumer show. They investigate allegations about a safety device in millions of homes, ask whether high street chains are failing when it comes to recycling and rank energy companies on cost, complaints and customer service. In Rogue Traders, Matt confronts a gardening firm whose elaborate lies have left customers thousands of pounds out of pocket, while Swab Mob checks in to a hotel chain accused of hygiene horrors.

Question Time (BBC1, 10.35pm)

THE topical debate show, presented by Fiona Bruce, invites an audience in Norwich to question a panel of politicians and others on subjects that have made the headlines over the past week. Appearing are Tory MP Brandon Lewis, Labour MP John Healey, DUP MP Jeffrey Donaldson, EU law professor Catherine Barnard and author and broadcaster Afua Hirsch.

Brexitcast (BBC1, 11.35pm)

BREXIT has dominated the news for more than three years. Britain’s pending withdrawal from the European Union has left millions fuming, while others are just desperate for some light relief as the process rolls on. If you are in the mood for a laugh, then this version of the hit podcast should take some of the sting out of the news as political editor Laura Kuenssberg, Europe editor Katya Adler, Europe correspondent Adam Fleming and political correspondent Chris Mason assess the latest goings on.
