BJP chief JP Nadda today targeted the opposition, accusing it of using “state machinery” to silence dissent in the states it rules. In a series of tweets, he said opposition should “adhere to political arguments when questioned on their failing” and assured the BJP workers that the party stands behind them. While the BJP chief did not mention any state or Chief Minister, his tweets were seen as targeting the government of Bengal’s Mamata Banerjee, who took on the Centre last week during the video conference with Prime Minister Narendra Modi.Coronavirus has been the latest flashpoint between the state and the Centre and over the last weeks, there has been an intense face-off between the two.
