New Delhi, Sep 7 (IANS): Hitting out at the Bharatiya Janata Party (BJP) for disrupting parliament, Prime Minister Manmohan Singh said Friday what was witnessed was "total negation" of democracy.

All "right thinking people", he added, should stand up to say that institutions should be allowed to function.

"We take pride in the fact we had a functional democracy. But what we have witnessed in this session is total negation of that," he said outside the parliament.

"And all right thinking people in this country should stand up and unitedly voice that come what may parliamentary institutions must be allowed to function with the norms as we have known them since India became independent," he told reporters.

Parliament was adjourned sine die Friday, after a month-long monsoon session that witnessed 13 days of disruption in 20-day session.

The session ended after the last day's proceedings too were disrupted by the BJP over coal block allocations.

The BJP has been demanding prime minister's resignation as they have alleged that the allocations were made when he was coal minister.
