A BJP MP on Monday demanded that the Centre intervene in West Bengal in accordance with the Constitution after a ruckus in the Assembly there, alleging that there was no rule of law in the state and party MLAs Suvendu Adhikari and Manoj Tigga were "attacked" inside the House.

Raising the issue during Zero Hour in Lok Sabha, BJP MP Saumitra Khan said, "We come to Parliament, we see sometimes there is one MP, sometimes 300, but in my seven years I have not seen anybody is attacked. But in West Bengal Suvendu Adhikari and Manish Tigga were attacked inside the Assembly. This has not been seen in the entire country."

"We need Article 355 as there is no rule of law in West Bengal, there is no government...There is no republic in West Bengal, we demand Article 355," he said.

Article 355 of the Constitution deals with an emergency provision by which the Centre can intervene and protect a state against external aggression or internal disturbance.

The West Bengal Assembly plunged into pandemonium on Monday as ruling TMC and BJP MLAs exchanged blows after saffron party legislators demanded a statement by Chief Minister Mamata Banerjee over "worsening" law and order situation in the state.
