New Delhi, Apr 26: The storm in Parliament over DMK minister of roads, highways and shipping T R Baalu, seeking gas supply at a concessionary rate to companies run by his sons is likely to remain in focus with the two Houses meeting again next week.

BJP has sought an explanation from the Prime Minister for his office having repeatedly written to the petroleum ministry in pursuance of Baalu's requests.

What the Opposition is hoping to capitalise on is Baalu's own admission that he did indeed seek to renew the allotments which had lapsed.

BJP denied that the NDA government had anything to do with cancelling the contract and spokesperson Ravi Shankar Prasad said that it had lapsed as certain contractual agreements were not honoured. Opposition NDA and AIADMK on Friday forced repeated adjournments in Rajya Sabha, until House was adjourned for the day.

Soon after question hour, Prasad waved a paper seeking to draw the attention of P J Kurien, who was in the chair.

When Kurien did not allow him to speak, an agitated Prasad was heard in the din saying that all he wanted to show was a copy of a letter by PMO allegedly asking ONGC to provide natural gas to companies belonging to Baalu's family. Kurien, however, did not allow him to speak.

Opposition members, who were in no mood to listen, demanded that PM should come to the House with a response to the letters purportedly written by PMO asking petroleum ministry to expedite the release of gas to companies owned by Baalu's family.

Samajwadi Party MP Janeshwar Mishra raised the issue soon after the House assembled saying the sword of discipline should not be used to put down democracy while JD(U)'s Sharad Yadav felt the chairman's action appeared to be "one-sided".

Keeping compulsions of coalition politics in mind, Congress on Friday responded to l'affair Baalu with extreme caution, stating its support for probity but refraining from hurting an important ally.
