Classic Doctor Who villains The Sontarans will reportedly make a return in the upcoming new series.

The race of humanoid aliens were revived by Russell T Davies in 2008 but have largely been restricted to background or fleeting appearances in recent years.

According to The Mirror, the Sontarans will be back in series 13 - currently being filmed - as part of an episode that will also guest star comedian John Bishop.

A source told the newspaper: "Instead of the blue armour they have worn in more recent series, the Sontarans have returned to a more traditional black and silver look.

"They are still short and exude plenty of menace. Should be fun."

The new series is expected to air at the end of 2021.
