The security cover for Tamil Nadu Chief Minister M.K. Stalin is downgraded from the Z+ category to the Z category following a review. The change applies to security provided to VIPs and VVIPs in Tamil Nadu, according to the reassessment process described by NDTV.
The review is carried out every six months and weighs multiple factors, including intelligence inputs, the nature and immediacy of threats, the level of public exposure, travel patterns, and the corresponding protection requirements. These criteria determine the security category assigned to the protectees.
Across the available reporting from NDTV, the emphasis is on the periodic nature of the assessment and the method used to decide security levels. The outlet does not cite a specific incident in the provided excerpt, focusing instead on the administrative review that results in the change from Z+ to Z.
