The Raj Thackeray-led Maharashtra Navnirman Sena has asked Congress president Sonia Gandhi [Images] to send back 25 lakh Biharis in Mumbai to their home state.

The MNS was reacting to the behaviour of Bihar MLAs who created unruly scenes during Bihar Governor R S Gavai's address to the state assembly on Friday wherein some of them reportedly raised slogans saying "Gavai go back to Maharashtra".

"This is not just an insult of the Governor but insult to crores of Dalits. To prevent further insult of Dalit leader like Gavai, Sonia Gandhi should call him back to Maharashtra.

But while doing so she should also see to it that 25 lakh Biharis from Mumbai are sent back to Bihar," MNS general secretary Shishir Shinde said.

He said, "The Congress and Lalu Prasad should first teach lessons of good behaviour to Bihar MLAs before giving advice to the people of Maharashtra."

MNS chief Raj Thackeray took a dig at the Bihar MLAs who created ruckus in the Assembly and said, "This was the reason (unruly behaviour) why he was opposed to outsiders in Maharashtra."

"Why did I have to launch an agitation to protect the culture of Maharashtra? The answer to this question lies in the manner in which the MLAs of Bihar behaved in front of the the Bihar Governor, who is a Maharashtrian," he said.
