"The House stands adjourned till 2:00 pm," announced Chatterjee soon after the Lok Sabha made obituary reference to Rajya Sabha member Nirmala Deshpande who died on Friday.

Chatterjee's sudden announcement caught the members unawares even as those in the Opposition benches, especially BJP, were seen sitting with finger on their lips.

The posture was prompted by the NDA's decision earlier in the day asking its members to remain silent in Lok Sabha to protest against the Speaker's decision to refer 32 MPs, mostly from the BJP, to the Privileges Committee for their "disorderly conduct".

Chatterjee's announcement came as Samajwadi Party leader Ramji Lal Suman sought to raise the controversial anti-North Indian statements of Maharashtra Navnirman Sena chief Raj Thackeray.
