The Murder of Jill Dando (BBC1, 9pm)

Twenty years ago this month, newsreader and Crimewatch presenter Jill Dando was shot and killed. The crime took place on her doorstep in the middle of the day and remains unsolved. This documentary tells the full story of the investigation, drawing on interviews with detectives, as well as Jill’s friends and family, and access to previously unseen photographs and material. The film looks back at how Jill’s murder shocked the nation – the Queen and then prime minister Tony Blair both paid their tributes – but also explores whether the sheer amount of public scrutiny also hampered the investigation. It explores the forensics, theories and decision-making behind the case.

Inside Britain’s Storms (STV, 9pm)

Although Britons are famously keen to talk about the weather, there isn’t always a lot to say about it, other than it’s a bit damp or mild for the time of year. That hasn’t been the casethis winter, though, as Britain has experienced floods, gales, lightning strikes and arctic snow fall, with two storms hitting during March alone. Using exclusive footage, eyewitness accounts and satellite tracking, presenter Becky Mantin follows some of these big weather events from the Met Office to the areas that bore the brunt of them, and in the process reveals the worst Mother Nature can throw at us. But can the documentary tell us whether these weather events will become even more common in the future and if we’ll all still be moaning if we can get another long, hot summer?
