Doctor Who stars Ncuti Gatwa and Varada Sethu are on this week's Radio Times

We have a terrific mix of stories for you in this week's Radio Times magazine.

You can meet the latest companion to board the TARDIS. Varada Sethu joins an illustrious list of actors to travel with the Doctor, from Peter Purves to Billie Piper. She plays Belinda who, in her first Doctor Who episode, looks confused and stressed. But that, she tells us, might have more to do with being set only two weeks after getting the job.

You can also meet Mek Mek, who sounds like an intergalactic monster but is, in fact, the unsung star of Beyond Paradise.

We also have a powerful personal reminder from historian and broadcaster Sir Simon Schama about the importance of never forgetting the Holocaust - and why he fears that is exactly what is happening.

But the most interesting story for me is our feature with William Mager and Matthew Gurney, writer and star of the new drama Reunion. They are both deaf, and their stories of making sure the deaf community were well represented and creating a mainstream drama in English and British Sign Language are inspirational - and a first for the BBC.

Interviewing Matthew using a BSL interpreter was also a first for our writer Gareth McLean. I hope that's proof you don't have to resort to time travel to see things changing for the better...
