Bhubaneswar, Sept. 22: Congress MLAs today sought the President's intervention to resolve the House impasse after blaming chief minister Naveen Patnaik and the Assembly Speaker for their failure to run it for the last two days.

"The chief minister was present all through when unruly scenes were orchestrated by the BJD MLAs and he did not intervene. At no stage, the Speaker explored the possibility of resuming the House business by calling an all-party meeting. There is every reason to believe that the chief minister, the Speaker and others conspired not to allow the proceedings of the House," said the Congress MLAs in a memorandum addressed to the President.

"This state of constitutional breakdown is something unheard of in the annals of democratic India. So your intervention is necessary to uphold the Constitution and law in the country," said the memorandum signed by Opposition leader Narasingha Mishra and other Congress MLAs.

The House could not transact its business for the second consecutive day today as the BJD MLAs disrupted proceedings by shouting slogans, forcing a series of adjournments.

Finally, Speaker Niranjan Pujari called a meeting of the business advisory committee in the evening where it was decided to have a discussion of the Mahanadi issue after Question Hour.

In another development, BJD MLA Byomokesh Ray expressed regret for raising slogan while the national anthem was being played in the House yesterday.

Mishra demanded resignation of chief minister Naveen Patnaik for his failure as the leader of House to ensure that the Assembly ran smoothly.

"The ruling party leaders are telling the media outside the Assembly that they are ready for discussion on any issue. But when they come to the House, they are scared to face any discussion and try to disrupt the proceedings," he said.

However, panchayati raj and law minister Arun Sahoo said: "The government is ready to face discussion on any issue. There will definitely be discussion on the Mahanadi issue in the House. But, we want to intensify agitation over this issue as the state's interest is involved here. If we don't, history will not forgive us."
