MI5 works closely with other UK intelligence agencies, such as MI6 (the Secret Intelligence Service) and GCHQ (Government Communications Headquarters), as well as international partners, to share intelligence and coordinate responses to global security challenges.
The Role of MI5 Agents

MI5 agents, or Security Service officers, are at the forefront of this critical work. Their roles are diverse and demanding, requiring a unique skill set and a deep commitment to national security. Here’s an in-depth look at the various roles and responsibilities within MI5.
