Janata Dal (United) leader KC Tyagi on November 10 said that NDA is losing only due to Covid-19 impact. “A year ago, RJD couldn't win a single seat in Lok Sabha polls. As per Lok Sabha results, JDU and allies were to win over 200 seats. In last one year, nothing has harmed brand Nitish or added to brand RJD, we are losing only due to Covid-19 impact,” said Tyagi.
