Political parties, including UPA ally Trinamool Congress, on Thursday night cried foul after the rajya sabha failed to pass the Lokpal Bill terming it as a "black day" for democracy and the opposition demanded resignation of the government for losing the "political and moral authority".

"The developments are sad, sad, sad... it was an orchestrated chaos," said Trinamool MP Derek O' Brien after the midnight drama when the rajya sabha was adjourned sine die without completion of debate on the Lokpal Bill.

Another party MP Sukhendu Sekhar Roy dubbed it as a "black day for Indian democracy" and said it was taken aback by the developments.

"We wanted clauses 63 to 97 to be deleted. That is our stand on Lokayuktas," O'Brien said.

BJP leader Arun Jaitley said the events were "well orchestrated" by the government as it wanted to "run away" from voting because of lack of numbers.

"It is a political and a moral defeat for the government. A government which runs away from vote has no right to remain in power... This government has been thoroughly exposed. It has conspired to avoid a vote. The government has lost its political authority and moral authority to rule," he said.

Noting that parliament is supreme, he said, "the government has succeeded in subverting the Indian parliament today. I am sure the people of the country will not spare this government."

As uproar continued, Ansari said, "an unprecedented situation has arisen. There appears to be a desire to outshout each other. There is total impasse. The house cannot be conduted in this noise. It requires orderly proceedings.

"I am afraid the Chair has no option but to reluctantly...," Ansari said and announced the playing of national song 'Vande Mataram', which is usually played at the end of a session before adjourning sine die.

"The house cannot be conducted in the noise. .. that (proceedings) requires orderly proceedings," Ansari said.

After the song was played, he said "the house stands adjourned sine die."

Later, members of BJP and Left staged protest in parliament complex for not passing Lokpal Bill in rajya sabha.

The Bill is likely to come up in the budget session.

Immediately a blame game started with the opposition attacking the government for failure to ensure passage of the bill while the Congress party sharply criticised the BJP for it.

Jaitley said it was a "well choreographed move" by the government to create disturbances through "ally" RJD and its motives were clear as early as 5 PM.

"The main reason is that the government had no numbers," he said, adding it was "political and moral defeat" for the government.

"This government has been thoroughly exposed. It has conspired to avoid a vote. It has no right to continue in office even for a minute," he said.

Earlier, parliamentary Affairs minister Pawan Kumar Bansal said as many as 187 amendments have been moved to the Bill and the government would require time to formulate its views if a "lacunae free" Lokpal was to be enacted.

Expressing government's commitment to fight corruption, Bansal said, "I assure the government will consider all amendments" and "we will come to the house".

He said it was government's prerogative to decide when parliament session should be convened.

He rejected the opposition's demand for further extension of parliament, saying any session in the New Year has to begin with the President's address.

His statement came after a 15-minute adjournment at 11.28 PM, which marked sudden disruption to the 11-hour debate.

The adjournment came when several members, particularly Left parties, created uproar, wanting to know whether the proceedings would continue after midnight as the extension of the Winter session was till only December 29.

minister of State for Personnel V Narayanasamy was replying to the 11-hour debate on the crucial bill when the uproar started.

"Nobody wants to listen to him. So why is he continuing," CPI(M) member Moinul Hassan said while Narayanasamy was replying.

Hassan, joined by party colleagues and members of BJP, wanted the chairman to clarify whether the house will continue after midnight or adjourn as the extension was only till December 29.

Ansari said there was still long way to go till midnight.

At this, CPI(M)'s Sitaram Yechury said Narayanasamy had the capacity to continue till 12 O'clock.

There was pandemonium and Ansari adjourned the house till 11.43 PM.

Earlier, BJP, BSP and Left pleaded with the chairman to give a ruling that the house will sit through the night and complete the business related to Lokpal.

"We are committed to fight corruption. We will sit through the night," Jaitley said.

"It is prerogative of the Chair how long the house should continue. It is not the prerogative of the government," he said.

Yechury also said the proceedings should continue beyond midnight and they were ready to sit through the night.

"If you don't have a plan, say it. There is no point in talking in vague terms," he said.

BSP leader Satish C Mishra later said "It is the prerogative of the chairman to run the house even beyond midnight and there have been precedents.

Earlier, RJD member Rajniti Prasad snatched the copy of Lokpal Bill and tore it before throwing it in the Well of the house. He was demanding that the Bill be withdrawn.

Mid-night drama in rajya sabha over Lokpal Bill

The rajya sabha witnessed a mid-night drama after the government said that there was no time left for voting and passage of the Lokpal Bill, while an angry opposition accused it of getting into a "hopeless" minority and running away from parliament.

As the prolonged debate, which started at 11 in the morning, was well past 11.30 at night, the opposition had a lurking suspicion that the UPA which is in minority in the Upper house was up to some game plan to avoid a voting.

Senior leaders from the BJP, Left and AIADMK kept on asking chairman Hamid Ansari whether business of the house would remain in continuity at 12 when the extended time period of the Winter session expires.

However, Ansari did not give a clear reply, but when pressurised, he adjourned the proceedings for 15 minutes at around 11.30 pm.

During the adjournment period, senior ministers, including finance minister Pranab Mukherjee and parliamentary Affairs minister Pawan Bansal were huddled, apparently discussing the strategy.

When the house re-assembled 11.43 pm, Bansal said since the government has received 187 adjournments to the Bill, it needed time to study the same. It led to angry protests from the BJP, Left, AIDMK, JD (U).

Earlier, two of the RJD members -- Rajneetin Prasad and Ram Kirpal Yadav, snatched papers from MoS parliamentary Affairs V Naryanasamy in the presence of prime minister Manmohan Singh. RJD supremo Lalu Prasad was in the visitors' gallery when his MPs were resorting to unruly behaviour.

While, the opposition was protesting against "choregraphed" plan of the government, Rajneeti Prasad even sat in the Well of the house evoking sharp response from Ansari.

Even after Ansari adjourned the house sine die following the National Song, the members of the opposition parties shouted and demanded resignation of the prime minister, who was leaving the house.

As the opposition members marching outwards, they went on shouting slogans -- "drama hai, drama hai, shame, shame".

Earlier, when Narayanasamy in his reply referred to the issue of Lokayuktas, Trinamool member Sukhendu Roy, was on his feet and shouted at him, "The minister is misleading the house. You have no right..."

As Narayansamy was booed frequently by opposition members which formed an overwhelming majority in the 243-member Upper house. Everytime the minister resorted to replying in his sore throat voice, he was booed.

The prime minister and finance minister Pranab Mukherjee who were the leading speakers in the Lok Sabha on the Bill did not speak in rajya sabha.

Trinamool Congress, a key ally of the UPA, was among the host of regional parties which were dead against the provision of Lokayuktas and charged that it was meant to cut into the autonomy of the states.

Even DMK and J&K National Conference had reservations on the clause.

While there were differenecs between the BJP and BSP and JD-U on the issue of reservation for OBCs, SCs, STs and minorities, their leaders remained in regular consultations in the house on what clearly appeared their strategy to corner the government.

BJP leader S S Ahluwalia was going to and fro the benches of the BSP and the Left parties where S C Mishra (BSP) and Sitarama Yechury (CPI-M) were seated.
