Maharashtra BJP chief Chandrakant Patil on Tuesday criticised the Congress for allegedly coming out with a toolkit in which social media volunteers have been asked to call a new mutant variant of Covid-19 as "Modi strain" or "India strain".

The Congress, however, has denied the allegations and has claimed the BJP was "propagating a fake 'toolkit' on 'Covid-19 mismanagement' and attributing it to AICC Research Department".
