Lok Sabha Speaker Somnath Chatterjee yesterday refused to speak out his mind on whether he will resign from the post after Left parties withdrew support to the UPA Government.

Asked about his next course of action in the wake of fresh political developments, the 79-year-old Speaker said, "I know it. You do not have to tell me that. You are not doing justice to the institution (of Speaker)."

Chatterjee's comments came as CPI(M) General Secretary Prakash Karat remarked that the Speaker would take his own decision on whether to quit the post.

He also declined to make any comment on the recent political developments. Asked to react on the political developments as he is the Lok Sabha Speaker, an apparently fuming Chatterjee said, "You are not treating me that way."
