Protesting against the Congress-led UPA government over the multi-crore coal block allocation scam, BJP here today exhibited cartoons mocking Congress leaders posted on various social networking sites.

Over half-a-dozen such hoardings were put around the Ambedkar circle where the party held a state-level protest against the scam.

The hoardings with caricatures of Congress president Sonia Gandhi, Prime Minister Manmohan Singh and other leaders allegedly involved in the scam were displayed for public viewing as part of the protest.

"The idea behind displaying hoardings was to highlight the coal scam among people effectively and impressively, and to make them aware of the approach of Congress," BJP state president Arun Chaturvedi said.

While addressing the crowds, the party leaders demanded Prime Minister's resignation and jail terms for those involved in the scam.

BJP also slammed the Congress-led UPA government over the hike in diesel prices.

"Corruption is rampant in Congress-rule, whereas inflation is skyrocketing. The government hiked diesel price yesterday which should immediately be rolled back," he said.

As a mark of protest, Chaturvedi reached the protest venue on a bicycle.
