Hyderabad, Aug 6 - Andhra Pradesh opposition legislators were suspended from the state assembly for a day after they stalled proceedings to demand that a house committee look into alleged irregularities by the Obulapuram Mining Company owned by Karantaka Tourism Minister G. Janardhan Reddy.

Speaker Kiran Kumar Reddy suspended 80 legislators belonging to the main opposition Telugu Desam Party (TDP), Telangana Rashtra Samiti (TRS), Communist Party of India (CPI) and Communist Party of India-Marxist (CPI-M) after Legislative Affairs Minister K. Rosaiah moved a resolution.

As soon as the house re-assembled after being adjourned for the second time on the issue, the opposition legislators were on their feet, pressing their demand for a house committee. They raised slogans in favour of their demand even as Rosaiah, who is also minister for finance, tried to go ahead with his reply to the debate on the budget.

Amid utter pandemonium, Rosaiah moved a resolution for suspending the members and it was passed by a voice vote.

The Praja Rajyam Party (PRP) of actor-turned-politician K. Chiranjeevi also lodged its protest over the government's refusal to constitute a house committee.

Earlier, Chief Minister Y.S. Rajasekhara Reddy turned down the opposition's demand for a house committee, saying the matter was pending in court. Denying any irregularities in granting mining lease or in mining activities, the chief minister alleged that the opposition was creating hurdles in the path of industrialisation and development.

'You are creating doubts in the minds of investors coming to the state,' said the chief minister, who also pointed out that an all party delegation of legislators visited the mines two years ago and found no irregularities.
