"Lalu brand of MLAs' were responsible for undignified treatment to the Governor, who hails from Maharashtra," the party said.

In an editorial in its mouthpiece Samana, the Sena said "the Bihar MLAs have the temerity to tell the Bihar Governor to go back to Maharashtra but when it comes to Sonia Gandhi who is a foreigner, they behave in an subservient manner."

"The key of free India is with the foreigner Sonia Gandhi. Her government runs on the support of Lalu. First show some guts to raise slogans against Sonia asking her to go back to her own country," the editorial said.

The editorial criticised the behaviour of Bihar MLAs who created unruly scenes during Gavai's address to the Assembly last week wherein some of them reportedly raised slogans like "Gavai go back to Maharashtra" because "Biharis were not safe in Maharashtra".

The incident in the House came in the wake of attack on the north Indian migrants in Mumbai and parts of Maharashtra by Raj Thackeray-led Maharashtra Navnirman Sena (MNS).

The editorial said Gavai is a balanced person who knows how to uphold the dignity of the post he holds. That is why he said "the day I came here as the Governor of Bihar, I became a Bihari". How many Biharis in Mumbai can hold such a view? the Marathi paper, edited by Sena chief Bal Thackeray, asked.

It said the Maharashtra-Karnataka boundary row is rankling since the last 60 years. Every Chief Minister of Karnataka "harasses" the Marathi-speaking people of Belgaum region.
