Stepping up his attack on the ruling Shiv Sena in Maharashtra, Maharashtra Navnirman Sena chief Raj Thackeray on Wednesday tweeted an old video of late Sena founder Bal Thackeray in which the latter was seen saying the day his party comes to power, praying of namaz on roads will be stopped and loudspeakers from mosques will be removed.

Raj Thackeray had on Tuesday urged people to play Hanuman Chalisa on loudspeakers on Wednesday wherever they hear loudspeakers "blaring azaan (Islamic prayer call)".

In an open letter, the MNS leader had asked people to lodge complaint with police by dialling 100 if they are disturbed by the sound of 'azaan'.

In the 36-second video tweeted on Wednesday by the MNS chief, Bal Thackeray was seen draped in a saffron shawl with the Shiv Sena symbol in the background.

The Sena supremo was seen in the video saying, "The day my government comes to power, praying of namaz on roads will be stopped because religion should be such that it doesn't create an impediment in national development."

"If our Hindu religion is creating an impediment then tell me, I will take care of it...Loudspeakers will be removed from masjids," Bal Thackeray said in the old clip.

The Sena founder died in November 2012.

His son Uddhav Thackeray currently heads the three-party Maharashtra government, comprising the Shiv Sena, the Nationalist Congress Party and the Congress.

The video clip comes after MNS workers played Hanuman Chalisa on loudspeakers near some mosques on Wednesday to protest the use of loudspeakers during 'azaan', following instructions from Raj Thackeray.
