Speaking on the Steve Wright in the Afternoon show on BBC Radio 2, Torchwood star John Barrowman confirmed that he has signed up to return to the series.

After the success of the five night Children of Earth, Barrowman said that Torchwood would be returning to a 13 instalment episodic format for its fourth season. No official production date has been set for the new series, although creator Russell T Davies previously indicated he expected it to get started early in 2010.

Barrowman also told the programme that there were no current plans for Captain Jack Harkness to encounter the 11th Doctor, played by Matt Smith, who takes over the title role in Doctor Who from David Tennant in the New Year's Day special, The End of Time, Part 2.
