Can I Improve My Memory?, 8pm, C4
Former Strictly judge Len Goodman, ex-EastEnder Nina Wadia, retired boxer Chris Eubank, presenter Anna Richardson and Love Island winner Amber Gill join host Sandi Toksvig as C4’s memory enhancement show – which previously aired as a one-off special in 2019 – returns for a full series. With help from memory experts Ed Cooke and Dr Tharaka Gunarathne, they must each memorise lots of information on a topic they know very little about – Len, deliciously, is assigned 90s US hip-hop. It’s thoroughly entertaining and full of useful tips on how to train your brain to work more effectively.

The latest updates, reviews and unmissable series to watch and more!
The second in this three-part series continues in the 1980s, a decade with contrasting highs and lows for the princess who had gone from being totally unknown to the most photographed woman in the world in a matter of months. Designer Bruce Oldfield talks about the way in which he helped her to change her style, which made her stand out at the many charity balls she attended. Celebrity astrologer Penny Thornton, meanwhile, tells us that the first time Diana consulted her, she said, ‘I just want to know that there’s light at the end of the tunnel,’ revealing how low she felt at that time. But as the decade went on, Diana’s confidence grew as she became more independent and represented causes and charities close to her heart.

Our NHS: A Hidden History, 9pm, BBC1
No one brings history alive like David Olusoga, the historian who makes the past personal, emotional and relevant and this film about immigration and the NHS is no exception. Here, he tells the story of the people who came from overseas to staff the new National Health Service and gave so much to this fantastic institution. David talks to some of them about the racism that they faced but he also celebrates their remarkable achievements.
