Speaking to reporters here, CPI(M) general secretary Sitaram Yechury demanded that the Centre take action given some TMC Parliamentarians have been accused of taking bribe and come to a "speedy conclusion" in the matter.
The party said the Election Commission too should take cognisance of the "sting" and intervene as the "disclosure" has come ahead of the assembly poll and "the money could be used to influence or intimidate voters" during the election.
"We demand that there should be a thorough investigation into this," Yechury said.
Yechury also dismissed TMC's claim that its political rivals were behind the "smear campaign" and asked West Bengal's ruling party to not "shy away" from a probe.
The Rajya Sabha member also stated that in case the BJP-led central government doesn't not take action in the matter, it will underscore again "match-fixing" between the NDA major and TMC, which he claimed, was already evident with CBI's alleged "go-slow" approach in Saradha chit fund scam, in which Trinamool leaders are accused of being involved.
