New Delhi (PTI): Attacking the UPA government for the "shocking" way of treating Parliament, the CPI(M) on Thursday demanded sine die adjournment of the House so that a full- fledged Winter Session could be convened next month.

Noting that this year Parliament has been in session for less than 40 days, the CPI(M) Polit Bureau said that the next session should be a full-fledged Winter Session and "not a farcical continuation" of the July 21-22 session.

"Parliament will have to be adjourned sine die so that the Winter Session can be convened in December. The presiding officers have the duty to see that this travesty of Parliamentary democracy is not perpetuated," the party said.

The CPI(M) noted that the UPA government refused to convene the Monsoon Session and it then announced that a continued session of the July 21-22 special trust vote would be held from October 17 to November 21.

"Now, barely a week after the convening of Parliament, it is being adjourned again on October 24. This exposes the narrow partisan interests which dictated the indefinite postponement of the Monsoon session and the doing away with of the Winter Session," the Politburo said in a statement.

It said this "gross contempt" for Parliament is compounded by the refusal of Prime Minister Manmohan Singh to honour his own commitment to seek Parliamentary approval for the nuclear deal.

The party said if the government does not convene a fresh session, it would consult with all other like-minded opposition parties to decide on the next course of action.
