The BBC has confirmed Jodie Whittaker will step down as Doctor Who at the end of 2022.

Whittaker will star in two specials already planned for 2022, as well as an additional final feature-length adventure for the Thirteenth Doctor.

Series showrunner Chris Chibnall will also leave the show.

Whittaker stepped aboard the TARDIS to begin filming in 2017, taking over from Peter Capaldi.

“In 2017 I opened my glorious gift box of size 13 shoes. I could not have guessed the brilliant adventures, worlds and wonders I was to see in them,” said Whittaker. “My heart is so full of love for this show, for the team who make it, for the fans who watch it and for what it has brought to my life. And I cannot thank Chris enough for entrusting me with his incredible stories.

“We knew that we wanted to ride this wave side by side, and pass on the baton together. So here we are, weeks away from wrapping on the best job I have ever had. I don’t think I’ll ever be able to express what this role has given me. I will carry the Doctor and the lessons I’ve learnt forever.

“I know change can be scary and none of us know what’s out there. That’s why we keep looking. Travel Hopefully. The Universe will surprise you. Constantly.”

The BBC said it will announce a new generation of Doctor Who “in due course”.
