Bharatiya Janata Party President Amit Shah and Union Home Minister Rajnath Singh would attend a party workers convention tomorrow to sound the bugle for assembly elections to be held later this year.

"Our leaders Amit Shah and Rajnath Singh will launch the campaign for Bihar assembly polls at the mega workers' convention. At least three workers from each of the around 62,000 booths in the state will participate in it," state BJP president Mangal Pandey told reporters.

"They will apprise the workers of the steps taken by Prime Minister Narendra Modi's government for the development of Bihar. They will take the message to each and every house in villages. They will ask voters to take a vow to remove jungle raj-2 from the state," Pandey said.

Senior BJP leader and former Deputy Chief Minister Sushil Kumar Modi said as the event was being organised on the occasion of 125th birth anniversary of Dalit icon B R Ambedkar, the workers will take a pledge to avenge the 'insult' to former Chief Minister Jitan Ram Manjhi, a mahadalit, allegedly by Chief Minister Nitish Kumar and RJD President Lalu Prasad.
