Poll authorities have issued a notice to BJP's Hari Nagar candidate Tajinder Pal Singh Bagga over his campaign video-song, asking why its expenditure should not be added to his poll-expenses, officials said. "The MCMC of West Delhi district had sent an email raising suspicion of paid news in his campaign-video-song 'Bagga Bagga Har Jagah', following which the notice was sent," a senior official said.
