Doctor Who casts beloved TV presenter in surprise guest role as show is rocked by shock death

TELLY presenter Davina McCall is to guest star in this year’s Doctor Who Christmas special.

And the role won’t be too challenging — as she will play a version of herself.

Davina, 55, will feature alongside a new Doctor played by Ncuti Gatwa and his assistant Ruby Sunday (ex-Corrie star Millie Gibson).

A source said Davina welcomes Ruby on to a genealogy show, like her ITV programme Long Lost Family, as she seeks her birth parents.

But in a bizarre twist, the host later gets crushed by a falling Christmas tree.

The source said: “The Christmas special is a huge deal for the BBC — this year especially so, as it’s Ncuti and Millie’s first.

“The Davina storyline is one element of the big festive episode on the table.”

Earlier this year, script editor Scott Handcock said “a guest star from 2005” would return for the special.

Davina provided the voice of the Davinadroid in an episode called Bad Wolf in 2005.

Fans have speculated other names could include Simon Pegg, who played The Editor — a shadowy figure who controlled more than 600 TV channels.

The source said: “As well as Davina, other guest stars from 2005 included Simon Callow and Annette Badland but Simon Pegg’s character could fit nicely alongside Davina’s role.”

Sex Education star Ncuti, 30, will take over from David Tennant, who is returning as the 14th Doctor in this year’s 60th anniversary specials.
