Raising the issue, Communist Party of India [ Images ] - Marxist's Basudeb Acharia sought a white paper on the price situation, saying the government had 'failed' to take any steps to curb the rising trend of prices.

He was supported by SP chief Mulayam Singh Yadav [ Images ], as several members from the Bharatiya Janata Party [ Images ], Rashtriya Janata Dal, Bahujan Samaj Party and Biju Janata Dal joined the Left parties on the issue.

The leaders included BJP leader Gopinath Munde [ Images ], BJD leader Bhratruhari Mahtab and BSP leader Dara Singh [ Images ] Chauhan.

"We have raised the matter a number of times in the House, but there has been no response from the government and the prices have continued to rise. We demand that the government come out with a white paper and take action to check the rising prices," Dasgupta said.

Acharia wanted the concerned minister to reply and urged Speaker Meira Kumar [ Images ] to 'put pressure' on the government to reply to their demands. However, there was no response from the treasury benches, which prompted the entire Left bloc to stage a walk out.

CPI-M [ Images ] member Ramchandra Dome also took the government to task on 'sky-rocketing prices' and said the Left parties were staging a massive rally outside Parliament to protest the government's policies which, he said, were causing the prices to rise.
