Spooks actress Miranda Raison claims that she is always worried about being axed from the show.

Raison said that the producers' willingness to kill off major characters means that she has to spend time trying to make friends with people on set.

Asked whether she was worried about being killed off, Raison told BBC News: "Always - it's not quite as bad as reading the scripts and wondering if it's you going to be you next. I've heard that you get a call from a producer saying, 'can I come over?'

"You can pretty much guarantee that it's not going not be good news. I'll just try and stay friends with everybody and suck up."
