Trinamul’s Diamond Harbour MP and party general secretary Abhishek Banerjee campaigned in Murshidabad’s Sagardighi on Sunday afternoon ahead of the February 27 bypoll.

The bypoll was necessitated in the wake of Trinamul MP Subrata Saha’s untimely death in December.

Abhishek was at the Dighir More grounds to campaign for Trinamul candidate Debashish Banerjee, a relative of chief minister Mamata Banerjee. Abhishek tore into Cong ress candidate Bairon Biswas, alleging a Congress-BJP nexus in Sagardighi.

He told the crowd that Biswas would join the BJP “within 24 hours” if he won.

“He (Biswas) is in cahoots with the BJP and always has been,” said Abhishek, unfurling a flex banner showing Biswas and Trinamul turncoat Suvendu Adhikari in a photo reportedly from the time when the latter was still with the ruling party.

“So a vote for the Congress (in Sagardighi) is a vote for the BJP,” Abhishek added, before proceeding to lay bare the BJP’s purported communal designs.

“A BJP leader has made a speech in Murshidabad saying Hindu areas should vote only the BJP and Trinamul shouldn’t be allowed to gain a stronghold in minority vote banks,” said Abhishek, before proceeding to play a voice clip ostensibly of Adhikari stating the above.

Abhishek termed Behrampore Congress MP Adhir Chowdhury a “Mir Jafar” — a sobriquet commonly used to describe a traitor in Bengal — given his recorded preference for travelling only with central security.

Abhishek said any block in Sagardighi without Trinamul majority would be deemed “Mir Jafar” as well. Minority voters in Sagardighi form around 66 per cent.
