The BJP has approached the Election Commission, Income Tax and Enforcement Directorate alleging that Patnaik misled the people by showing different amounts as his election expenditure in different documents.
"The allegations raised by BJP are false, malicious and fabricated," BJD spokesman and Rajya Sabha MP Pratap K Deb and Lok Sabha member Pinaki Mishra said in press conference.
"The facts related to the financial transactions of the party account has been deliberately twisted so that it seems like some dubious transactions," he said.
Patnaik won from Hinjili assembly constituency in 2014.
