Delhi BJP on Sunday complained to the Election Commission and sent a defamation notice to AAP seeking Rs 500 crore in damages after it tweeted a video that showed Manoj Tiwari dancing to the tune of Aam Aadmi Party's campaign song for the forthcoming assembly polls. The video appears to be an edited version of Tiwari's Bhojpuri albums with "Lage Raho Kejriwal" soundtrack.
