Spy drama Spooks is being axed after almost a decade on air.
The BBC One show will end at the conclusion of its next run, which begins in September.
Programme-makers said it was the right time to make way for "new spy dramas which reflect the changing world around us."
The show has become renowned for killing off many of its main characters since its launch in 2002.
Show bosses say the series will come to a "natural end" with a plot which continues to revolve around the relationship between Harry Pearce (Peter Firth) - pictured -and Ruth Evershed (Nicola Walker).
Executive producer Jane Featherstone - of independent production company Kudos - said:
"The heart of the show has become those two characters and I feel they own it.
"We've followed the arc of their personal story and I think they've brought us to a natural end."
Stars of the series have included Rupert Penry-Jones and Hermione Norris, while Hugh Laurie, Lindsay Duncan and Benedict Cumberbatch have been among the featured guests.
The final, 10th series sees Alice Krige and Jonathan Hyde joining the cast, with Simon Russell Beale returning as home secretary.
BBC drama controller Ben Stephenson said the show would bow out with "what promises to be a fittingly high-octane thrilling finale."
