Cracking the whip, Lok Sabha Speaker Meira Kumar on Thursday suspended 18 MPs from Andhra Pradesh for rest of the session after unprecedented pandemonium broke out in the House over the Telangana issue.

Ms. Kumar announced the decision soon after the House met at 2 pm after being adjourned in the wake of the ruckus created at noon by pepper spraying and fisticuffs among members opposing and supporting Telangana.

She named the members and said they had been suspended under Rule 374 A, which says that a member can “be suspended from the service of the House for a period not exceeding the remainder of the session” for disregarding “the authority of the Chair or abusing the rules of the House by persistently and wilfully obstructing business.”

“They may forthwith withdraw from the precincts of the House,” Ms. Kumar said.

Those suspended include L. Rajagopal, expelled Congress member who had earlier sprayed pepper gas from a canister in the House, causing chaos. TDP member M Venugopala Reddy, who broke the mike, was also among the MPs suspended.

Others suspended are Sabbam Hari, Anantha Venkatarami Reddy, Rayapati Sambasiva Rao, SPY Reddy, M Sreenivasulu Reddy, V Aruna Kumar, A Sai Prathap, Suresh Kumar Shetkar, KRG Reddy, Bapi Raju Kanumuri and G Sukhender Reddy (all Cong), Niramalli Sivaprasad, Nimmala Kristappa, K Narayana Rao (all TDP), and Y S Jaganmohan Reddy and M Rajamohan Reddy (both YSR Congress).
