Raipur, April 23 (IANS) The Congress party in Chhattisgarh with a new state unit chief is preparing a comprehensive charge sheet against the Bharatiya Janata Party (BJP) government in a bid to expose it on corruption issues, party sources said Saturday.

Newly-appointed state chief Nandkumar Patel was instructed by the central leadership during his trip to New Delhi this week to step up the campaign against the BJP regime and prepare a charge sheet highlighting the corruption and scandals in key government schemes and industrial projects, including recommendation of coal mines to private companies, sources said.

"Patel will soon set up a panel of party leaders to prepare the charge sheet against the BJP regime. The charge sheet will be filled with evidences and documents to be sourced using the Right to Information Act," a senior party leader told IANS.

The charge sheet will be handed over to President Pratibha Patil with a copy to Chhattisgarh Governor Shekhar Dutt in a bid to take on the BJP with an eye to returning to power in the assembly polls due late 2013.

The Raman Singh-led BJP government, ruling since December 2003, came to power after it handed down a crushing defeat to Ajit Jogi-led Congress government.

The Congress which is divided into various factions and sub-factions in the state, has hardly focused on taking on the BJP government since 2003, and its state leaders have hit the headlines often for publicly criticising one another.

But political analysts say that appointment of Patel as new state chief has raised hopes of the Congress comeback as he has good rapport with all the factions and also belongs to Other Backward Classes that make up nearly 50 percent of state's total 2.55 crore population.
