Patna: The Congress on Friday began a 'Pol Khol' (expose Nitish) yatra in Bihar to highlight the prevalence of alleged scams and misgovernance in the state.

The Yatra would cover all the 38 districts in Bihar. Flagging off the yatra, CWC member and in-charge of party state affairs Gulchain Singh Charak said during the campaign, party leaders would create awareness among the people about the alleged corruption and scams, loot and misappropriation of funds meant for development schemes as highlighted by the recent CAG report.

He demanded a CBI probe into the alleged misappropriation and embezzlement of public money in Bihar highlighted by the CAG.

A YC delegation would petition Prime Minister Manmohan Singh, Union Home Minister P Chidambaram and Governor Devanand Konwar for a CBI probe into the CAG report for the period ending on March 31, 2011, state youth congress president Lalan Kumar said.

Kumar described the CAG report highlighting Rs 22,5000 crore irregularities involving non-reconciliation of the Abstract Bill and Detailed Contingent Bill, besides loss, theft, defalcation and embezzlement of funds as 'the mother of all scams'.

The 'scam' is bigger than the fodder scam during Lalu Prasad's regime, he said. Bihar Pradesh Congress Committee president Chowdhary Mehboob Ali Kaiser and state Youth Congress president Lalan Kumar embarked on the yatra.

Gulchain Singh Charak flagged off the yatra after paying homage to seven martyrs at the Sahid Samarak here.
