In his first hard-hitting reaction after expulsion from the Communist Party of India-Marxist (CPI-M), Lok Sabha Speaker Somnath Chatterjee has said he was now a "sinner" in the eyes of the party, and asserted that he would see how far those spreading "canards" against him could go.

Chatterjee also promised to reply to the "canards" being spread against him "in a day or two".

"I am a sinner in the eyes of the CPI-M and not a gentleman. That's why they thought I deserved the summary expulsion," Chatterjee was quoted as saying in the Kolkata-based English daily The Telegraph on Sunday.

The Bolpur MP has been the target of a vitriolic attack by the Left leaders, who have branded him a "traitor", a "bourgeois" and one who always hankered for posts, after he defied the party diktat to step down from the speaker's post ahead of the July 22 trust vote in parliament.

"Let them say whatever they are saying. I would like to see how far they can go," Chatterjee said.

On allegations that he had "sided" with the government on the day of the confidence motion, Chatterjee said.

"I tried to fulfil my constitutional obligations impartially," he added.

Chatterjee also questioned the CPI-M's claim that it was compelled to come down hard on him as he remained stubborn on not resigning despite the party exempting him from the trust vote whip.

"If they were being so accommodating - to the extent of allowing me not to vote (against the government) - why were they goading me to resign?" Chatterjee told the daily.

The Speaker reiterated that he would visit Kuala Lumpur for the Commonwealth Parliamentary Association conference Aug 1-10 and preside over the Hiren Mukherjee Memorial Lecture by Nobel laureate Amartya Sen in the Lok Sabha on Aug 11.

He said that he was yet to decide on whether to continue in the post after August 11.

Karat speak

Meanwhile, CPI(M) general secretary Prakash Karat on Sunday said it was for Lok Sabha Speaker Somnath Chatterjee to decide whether he should continue in the post. Chatterjee was expelled from the party's primary membership for defying its directive by presiding over the special session of parliament.

"Whether he should continue as the speaker is for him to decide. But whether he should be in the party is for the party to decide," Karat said while responding to queries about Chatterjee's expulsion from the CPI-M and his continuance as the Lok Sabha speaker.

Karat, however, said there were provisions for appeal in the CPI(M) constitution against such expulsion orders.

He refused to comment to a query on whether party patriarch and former West Bengal chief minister Jyoti Basu has endorsed the party's stern action against Chatterjee.

"I don't want to comment on this," he said, when asked by the media as he emerged from the two-day deliberations of the party's West Bengal state committee.

Karat did not entertain any more posers on the issue, saying: "We have already issued a statement a few days ago. I have nothing more to say on this."

The CPI-M politburo expelled Chatterjee from the party's primary membership on Wednesday, a day after the United Progressive Alliance (UPA) government won the trust vote with a comfortable 19-vote margin.
