Currently appearing in space drama Outcasts, Norris played Chief of Section D Ros Myers between 2006 and 2008.

Interviewed to promote today’s Series 9 DVD release, Firth commented: “Well, Hermione’s gone, which is a big loss for all of us – largely because she great to have around in case there was any trouble, she could sort them out! She was with us for four years and I miss her very much – I miss her and her character.”

Spooks will return for a tenth series this Autumn.
