The Centre has provided armed 'Y' category CISF security cover to Trinamool Congress MP Kakoli Ghosh Dastidar from May 19, following a threat assessment by central agencies.
According to officials, the security arrangement was implemented with immediate effect after central agencies evaluated potential threats to the TMC MP.
The move has drawn political attention as it comes amid significant changes within the Trinamool Congress's parliamentary leadership.
Recently, party supremo Mamata Banerjee replaced Kakoli Ghosh Dastidar as the party's chief whip in the Lok Sabha and appointed senior MP Kalyan Banerjee to the post.
The decision to grant CISF protection was based strictly on security considerations and threat perception inputs and had no connection with internal political developments within the party.
