Two Doctor Who favourites have been confirmed to return to the show, just a week after Sex Education actor Ncuti Gatwa was revealed as the Fourteenth Doctor.
The BBC has confirmed that David Tennant and Catherine Tate are both set to join the show, reprising their roles as the Tenth Doctor and his companion Donna Noble.
Doctor Who's returning showrunner, Russell T Davies, said: "They’re back! And it looks impossible – first, we announce a new Doctor, and then an old Doctor, along with the wonderful Donna. What on earth is happening?
