The Thick Of It stars Rebecca Front and Peter Capaldi will be reunited in the new series of Doctor Who.
Front, who played put-upon minister Nicola Murray in the political satire, is making a guest appearance alongside Capaldi who played foul-mouthed spin doctor Malcolm Tucker before taking over the controls of the Tardis.
She will appear in two episodes that see the return of the shape-shifting Zygons.
The new series, which will be on screens this autumn, also includes guest appearances by familiar faces including Game Of Thrones star Maisie Williams, Michelle Gomez, Rufus Hound, Paul Kaye and Jaye Griffiths.
Show bosses announced yesterday that Capaldi and other cast members will join show writer Steven Moffat and meet fans at a three-day event dedicated to the show.
The Doctor Who Festival at London's ExCel Exhibition Centre will run over three days from November 13.
