BJP put up posters in Patna which asked RJD chief Lalu Prasad Yadav to apologise for allegedly disrespecting Dr BR Ambedkar. "It's about to be 7 days now, Lalu and Tejashwi Yadav, when will you apologise," the poster read. A video on social media purportedly showed Lalu Prasad's feet near a portrait of BR Ambedkar during his birthday celebration.
