Kolkata: Senior Trinamool Congress leader and strongman Anubrata Mondal underwent a minor surgery at the state-run SSKM Hospital here on Sunday, the hospital sources said. According to the doctors, Mondal, Trinamool Congress’ Birbhum district President, has been kept under observation as he is also suffering from high diabetes and high blood pressure. “Mondal was admitted to SSKM on Friday (July 5) with high diabetes. Today he underwent a fistula operation. We kept him under observation for the first two days as he had high blood sugar and blood pressure,” said the doctor monitoring Mondal.

Mondal, who shares a cordial relationship with West Bengal Chief Minister and Trinamool Congress supremo Mamata Banerjee, has been in news many times for making controversial statements in public, including asking the party activists to “hurl bomb at the police”. During the 2019 general elections in the state, Mondal was kept under strict surveillance on the polling day in Birbhum after he allegedly threatened the poll officials to work in favour of his party. However, the firebrand leader remained largely away from public eye after the 2019 poll results were announced. Though Trinamool Congress managed to hold on to the two Lok Sabha seats in Birbhum, the BJP, went ahead in a number of Assembly segments.
