MI5 reportedly opened a file on Labour leader Jeremy Corbyn amid concerns over his willingness to enter into dialogue with members of the IRA.
The security agency is believed to routinely keep files on people of interest, including political activists and campaigners. Archived documents have revealed Mr Corbyn attended several events supporting the militant Republicans during the 1980s and 1990s.
An unnamed source reportedly told The Telegraph: “If there was a file on someone, it meant they had come to notice. We opened a temporary file and did a preliminary investigation. It was then decided whether we should open a permanent file on them.”
A spokesman for the Home Office said they could neither confirm nor deny who M15 kept files on in the interests of national security.
