MI has a "National Security Intelligence Team." Unlike the NZSIS, GCSB, and National Assessments Bureau, MI lacks scrutiny from an intelligence watchdog but only has an internal monitoring team.
The UK's MI agency operates without external scrutiny like its counterparts in New Zealand (NZSIS), Australia (GCSB), and the United States (National Assessments Bureau). Instead of relying on independent watchdogs, MI relies solely on an internal monitoring team.
