"The Trinamool has won many seats but still they are not happy as they can't play a decisive role in the formation of next government. Before elections they had boasted they will be in control of the next government, but everything has gone in vain," Sinha said.
Sinha also made caustic comments regarding TMC candidate Subrata Bakshi's "drubbing" in Bhawanipore assembly segment, from where Mamata is an MLA.
He claimed if the Election Commission had been more active in "curbing the terror tactics of Trinamool", BJP would have won from at least 10 seats and the party's vote share would have gone up by at least 30 per cent.
"We will again complain to Election Commission to inquire against Sudhir Kumar Rakesh for his bias towards Trinamool Congress," Sinha said.
After BJP's spectacular performance in the polls, Sinha hinted that the verdict will further strenghten the party's base in Bengal.
"Already the exodus from CPI(M) to BJP has begun in Bengal. People from Congress and Trinamool have also started joining us. The assembly polls of 2016 will be fought between BJP to TMC," he said.
