The Trinamool Congress and the BJP have been locked in a verbal exchange over the JP Nadda-led party's planned Rath Yatra in Nabadwip in Nadia district of West Bengal. The BJP has now called it a "Parivartan Yatra", and said it is the media that has been calling the campaign programme Rath Yatra. The nuanced position comes after a PIL (public interest litigation) was filed in the Calcutta High Court seeking directions to stop it citing concerns over law and order.
