The ruling Trinamool Congress on Wednesday won by-elections to two wards in civic bodies in Bengal amid allegations by the Opposition BJP of electoral malpractices.

TMC candidate Bidhan Upadhyay bagged ward number six of Asansol Municipal Corporation in Paschim Bardhaman district by 5,475 votes. The TMC secured 6,683 votes, CPI(M) 1,208 and BJP 485, State Election Commission Secretary Nilanjan Shandilya said.

Papai Raha, the party's nominee in ward number 14 of Bongaon Municipality in North 24 Parganas district won by 2,118 votes. The TMC got 2,842 votes, BJP 724 and CPI(M) 332.

The by-election in Bongaon was necessitated following the death of TMC councillor Dilip Das, while in Asansol, it was because of resignation of elected TMC councillor Sanjay Chakrabarty.

The by-elections were held on August 21.
