“I categorically deny the allegations of Congress party which is false, mischievous and politically motivated,” BJP leader said.
“For the purpose of record, I will once again while denying these allegations like to reiterate that neither do I have any foreign account nor any investment/share in any foreign company,” he said in a statement.
At a press conference earlier in the day, Congress leader Jairam Ramesh had cited a previous report of International Consortium of Investigative Journalists to allege Mr Singh was holding offshore assets.
The BJP also rejected the Congress attack on Finance Minister Arun Jaitley as “false and foolish”.
Mr Ramesh had demanded that Mr Jaitley “recuse” himself from probe into Panama Paper leaks citing his sports promoter Lokesh Sharma, who reportedly held offshore companies.
“We reject such false and foolish claims. It’s ironical that Congress is making such claims as it is mother of black money. It looted the country and facilitated flow of illicit money abroad. Our government swiftly ordered a multi-agency probe. It had also set up a SIT to look into black money and passed a law in Parliament to curb it,” BJP National Secretary Shrikant Sharma said.
