Veteran Belfast journalist Vincent Kearney says revelations about MI5 monitoring left him facing one of the most serious labels possible: being treated as a threat to national security. The account has drawn attention because it involves an established reporter whose work depended on protecting confidential contacts.

Kearney said the issue was not abstract for him or his family. According to the report, his children used to joke that he was like James Bond because he would not use the home phone for work conversations. Instead, he would step outside to take calls on his mobile, reflecting the caution he felt was necessary around sensitive reporting.

The story also points to the damage such surveillance claims can do to a journalist's standing. Kearney heard from sources after the spy revelations that he might as well have been seen as an informer, a perception that could deeply affect trust in both the reporter and the people who speak to him.

The case is likely to sharpen debate over press freedom, source protection and the reach of security agencies in Northern Ireland. Even from the limited details available, the central issue is clear: a prominent journalist believes state surveillance cast suspicion over his work and the people connected to it.
