New Delhi | As Bihar prepares for phase one of assembly polls on November 6, the Election Commission has warned that bulk SMSes and audio messages during the 48-hour 'silence period' which starts before the conclusion of voting, is prohibited.

In a note issued on October 9 outlining campaigning restrictions, the poll authority said, political advertisements on any election matter in TV, cable networks, radio, cinema halls, use of bulk SMS/voice messages, audio visual displays in any polling area during the period of 48 hours ending with the hour fixed for the conclusion of the poll for any election in the polling area is prohibited.

No political advertisements are to be released to any internet-based media/websites, including social media websites, by political parties or candidates without pre-certification from the respective MCMC, it cautioned.
