Congress has asked BJP to disclose the source of its huge expenditure on election campaign. Addressing a press conference in New Delhi today, party spokesperson Anand Sharma alleged that the main opposition party is spending an unprecedented sum of 10,000 crores rupees in the election campaign. He said, extravagant use of money for raising personality cult of a person is dangerous for democracy. Sharma also claimed that the ten percent of the total budget of BJP's election expenditure is white money while the rest is black.
