Former Trinamool Congress minister Upendra Nath Biswas and the man who supported Mamata Banerjee when she ousted the 34-year-old Left Front in 2011, has resigned from the party.
On Wednesday morning, the veteran investigator and former IPS officer submitted his resignation from TMC by mailing his letter to party president Subrata Bakshi. He has also resigned as the “CBI advisor to Trinamool Congress, core committee, any other membership or any other membership of the party.”
Biswas, whom Mamata affectionately called “Upen da” retired as additional director of the CBI in 2002. He was one of Mamata’s most trusted lieutenants when she spearheaded the land movement before wresting Bengal a decade ago.
Biswas came into the limelight for sending Lalu Prasad Yadav to jail, leading the fodder scam cases against him.
The move comes ahead of the last phase of the eight-phase Assembly elections in West Bengal. The results are due to be declared on May 2.
