Sue Perkins: Along the US-Mexico Border

9pm, BBC One

Fresh from her light-hearted jaunt to Japan in 2019, Sue Perkins takes a somewhat more serious approach to the borderlands between the US and Mexico, examining how Trump’s nationalistic rhetoric is affecting people’s lives on both sides. We open in Tijuana, where Perkins hears from migrants who hope to get over the border, as well as from US retirees living in the area and medical tourists looking for cheap dental work. Concludes tomorrow evening. Ammar Kalia
