A new logo for the show was also unveiled to celebrate the show's 60th anniversary next year and features a diamond emblem, a traditional marker for a 60th anniversary.

Millie Gibson was announced to be joining the show during Children in Need on Friday night. The BBC confirmed she would debut in Doctor Who over the festive season in 2023.

She is best known for playing Kelly Neelan in Coronation Street for which she won Best Young Performer Award at The British Soap Awards earlier this year.

The 18-year-old said of being cast in Doctor Who: "Whilst still being in total disbelief, I am beyond honoured to be cast as the Doctor’s companion. It is a gift of a role, and a dream come true, and I will do everything to try and fill the boots the fellow companions have travelled in before me.

"And what better way to do that than being by the fabulous Ncuti Gatwa’s side, I just can’t wait to get started."

Doctor Who will return to the BBC in November 2023 for the show's 60th anniversary with Tennant to star as the Doctor in three specials before Gatwa takes over the role.
