Jodie Whittaker will step down as the 13th Doctor in Autumn 2022, the BBC has confirmed.

Whittaker broke records when her fist episode as the Doctor in October 2018 was watched by 11.5 million viewers, the show’s biggest audience in almost a decade.

She said in a statement: "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.

"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."

She added: "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 are yet to announce her replacement with speculation rife ahead of the show’s 60th anniversary in 2023.

Who are the celebrities in line to replace Jodie Whittaker in one of the most iconic roles in British television?
