Kolkata/IBNS: West Bengal Chief Minister Mamata Banerjee on Thursday launched  a scathing attack on state Congress president Adhir Ranjan Chowdhury referring to his late daughter and driver in her response to the Trinamool Congress' debacle in Sagardighi assembly by-election.

When she was asked about Chowdhury's claim that the minority votes are moving away from the Trinamool, Banerjee said, "I won't answer. Let the minority people answer that. Why was Bogtui an issue in the Sagardighi bypoll?"

"He (Adhir Ranjan Chowdhury) is saying so many things but can he answer on his daughter's suicide, driver's murder? I know a lot of things. Don't trigger me to speak out," the Chief Minister said.

In reply, Chowdhury told a local news channel, "The Chief Minister has every right to talk about it. But will she have the patience to listen to my answers?"

In less than two years after being routed from the state assembly, the Congress, of course backed by the Left, made its comeback trouncing the ruling Trinamool Congress in the minority-dominated Sagardighi assembly constituency of West Bengal's Murshidabad district.

Congress candidate Bayron Biswas defeated his nearest rival from the Trinamool, Debashish Banerjee, by 22,986 in the seat which saw Trinamool's victory in the last three state elections held in 2011, 2016 and 2021.

In the 2021 elections, Trinamool candidate Subrata Saha (whose death necessitated the bypoll) won for the third consecutive term by over 52,000 votes.
