Speaking at an election rally here, Banerjee also said a "section of media" is with the Opposition parties and she will "expose" them later.
"We have done a lot of developmental work in the last four years. No other political party in the country has been able to usher in so much of development. But the Opposition parties can't see that development. They are only campaigning to malign us," Banerjee told an election rally here.
Banerjee said she will seek justice from the people of Bengal. "We have full faith in them. The Opposition parties want to divide West Bengal. But as long as I am alive, I won't let them do that," she said.
Her statement comes in the backdrop of the telecast of a sting video by a web portal purportedly showing some TMC leaders accepting bribe to help a fictitious private firm.
While listing out various developmental work her government has achieved, Banerjee said every section of the society has benefited from the schemes.
