New Delhi, April 27 (IANS) The Lok Sabha was adjourned as opposition leaders protested against rising prices Tuesday. Leader of opposition Sushma Swaraj also lashed out at Prime Minister Manmohan Singh for making a statement outside the house on a JPC probe on the phone tapping and IPL.

The prime minister had Monday night told reporters on the sidelines of the defence investiture ceremony at Rashtrapati Bhawan that the phone tapping and IPL controversy were not fit cases to constitute a joint parliamentary committee (JPC).

Sushma Swaraj said she was "shocked to see in the newspaper" that the prime minister had made a statement rejecting the Bharatiya Janata Party's demand.

"This is not an ordinary thing. This is an insult to the august house," she asserted, amidst a ruckus by members of Samajwadi Party and Rashtriya Janata Dal over rising prices.

Lok Sabha Speaker Meira Kumar adjourned the house till noon as opposition members gathered near her podium raising slogans against rising prices.
