There's still no official suggestion that Jodie Whittaker will be leaving Doctor Who any time soon, but that hasn't stopped the exit rumours from swirling, leading to inevitable speculation about who will play the coveted role in the future.
Even Mandip Gill, who plays loyal companion Yaz, has been chatting about who might steer the TARDIS in the years to come.
Chatting to Meera Syal, in character as Granny Kumar for her Radio4 show, 'Gossip and Goddesses with Granny Kumar', Gill says she believes the Doctor will one day be played by a woman of colour.
Syal asks directly if Gill thinks an actress of colour will ever play the Doctor, to which she says, “Yeah, I do. I think there’s a long way to go but there’s definitely room for change. And actually I think at the BBC and at Doctor Who they are very open and forward-thinking, so yes.”
Gill, who appears alongside actress Josette Simon on the show, also reflects on how excited she was to be cast in Doctor Who in the first place. “I couldn’t believe my luck. I’d filmed Casualty the January before and that was in the same building," she says.
'We were at the top of the hallway and when I finished Casualty, they walked us to the canteen and they were like, 'Don’t go in that door, that’s for the Doctor Who people!’. There and then I thought I’d never be in Doctor Who... Cut to six, seven months later and you know what? I’m like ‘Don’t go up there… that’s for Casualty!'”
