Unforgotten actress Sara Powell, The Split’s Annabel Scholey, Cold Feet actor Gerald Kyd and The Crown’s Penelope McGhie will also feature.

“It’s our biggest adventure yet with so many brilliant characters to fall in love with.

“We had a blast making it.”

Whittaker, who has played the Time Lord since 2017, said in July she will be leaving the sci-fi drama.

She will feature in the upcoming series before exiting the BBC show in a trio of specials next year.

The first special will air on New Year’s Day 2022, the second will be later in the spring and the third, when the Doctor will regenerate, will air in autumn 2022 and will form part of the BBC’s centenary celebrations.

The new series of Doctor Who begins on October 31.
