NEW DELHI: Congress president Sonia Gandhi on Thursday criticised the government for "unplanned" implementation of the countrywide lockdown evoking a strong response from Union home minister Amit Shah who accused Congress of playing "petty politics" over the coronavirus outbreak.Addressing a meeting of the Congress Working Committee (CWC) through video conferencing, Gandhi said the countrywide lockdown had caused "chaos and pain" to millions of migrant workers."The 21-day national lockdown may have been necessary but the unplanned manner in which it has been implemented has caused chaos and pain in the lives of millions of migrant workers all over India," she said.Hitting back, Amit Shah asked Congress to think about national interest and not mislead the people."Under PM Narendra Modi's leadership, India's efforts to fight the coronavirus are being lauded domestically and globally. 130 crore Indians are united to defeat Covid-19. Yet, the Congress is playing petty politics. High time they think of national interest and stop misleading people," he said in a statement.The former BJP president said it has been an "old habit" of the Congress that it has always walked a different path in matters of national interest, and that it has sought to divide the country for its "selfish interests".The Congress president, JP Nadda said, is being "insensitive and indecent" in her comments."The entire country is today fighting against Covid-19 unitedly under the leadership of Prime Minister Narendra Modi. At such a time, Congress president Sonia Gandhi's statement is insensitive and indecent. This is not the time for politics but to serve the nation unitedly," Nadda said.Information and Broadcasting Minister Prakash Javadekar said the need of the hour for everyone is to join hands and to take on the pandemic unitedly.There will be time for politics after the coronavirus is defeated, this should not be done now, he told reporters.At a meeting, the CWC accused the government of not giving any serious thought to the deteriorating economic situation in the country, even as it said the government has erred in adopting the policy of limited testing for Covid-19.The CWC called upon the government to take steps to re-start the engines of economic growth.
