MI5 and Blue Peter, the BBC's long running children's programme, have teamed up to try to find potential 007s of the future.
As part of a unique competition, three lucky youngsters will be offered the chance to go on a very special mission behind the scenes at HM Secret Services, in London.
Their visit to MI5 headquarters will be filmed for the programme - the first time television cameras have ever been allowed into the top secret building at Thames House.
The decision by MI5 to open its doors to television cameras is a milestone in the history of the secret services.
Viewers aged between the ages of eight and 14 will be invited to apply to 'Project Petra' – named after one of the show's earliest pets – through the Blue Peter website to see if they have what it takes to become a spy.
The top eight candidates will be invited to attend a special 'spy school' weekend, where they will be put through their paces in a rigorous selection procedure consisting of mental and physical challenges. Three will eventually be chosen to head to the secret base.
Bestselling author Anthony Horowitz, who has written the Alex Rider series of books about a teenage agent, is on the selection panel to find the three CBBC Intelligence Officers.
