West Bengal CM Mamata Banerjee led TMC hit out at the BJP after the latter announced that it will provide free vaccines in the state once it is voted to power in the ongoing assembly elections. Bengal BJP tweeted on Friday to write that Covid-19 vaccine will be provided free of cost to everyone as soon as it comes to power. TMC's Derek O' Brien has called it a 'jumla'. Derek recalled BJP’s free vaccine assurance during Bihar elections and sought to know if the promise has been fulfilled. ‘2 phases of voting left and BJP says this. Don't believe BJP’, the TMC MP said.
