Newspaper Berlingske reported on Wednesday comments by the lawyer, Stephen M. Kohn.
Kohn said that Danske Bank refused during the summer to repeal Wilkinson’s general confidentiality agreement, preventing him from contacting authorities over suspected money laundering.
“Danske Bank’s confidentiality clause forbade Mr. Wilkinson from communicating with police and prosecution authorities. And the bank refused to issue a general permission which would have lifted these prohibitions,” Kohn said in a statement to Berlingske.
“Not until two weeks ago did Danske Bank waive the confidentiality agreement in relation to Mr. Wilkinson’s communications with the Danish prosecution service,” he also said.
But the bank, Denmark’s biggest lender, said it did not agree with the description of events given by Kohn.
“We do not recognise this representation of the events,” Danske Bank senior press officer Kenni Leth told Ritzau in a written statement.
“We have responded positively to all approaches regarding the whistleblower and have stated in writing that the whistleblower was permitted to speak with both Danish and Estonian authorities,” Leth added.
Danske Bank did not give the whistleblower full freedom from confidentiality during the summer because Kohn asked for exception from clauses related to bank secrecy laws, which Danske Bank is not permitted to give, Leth said.
A new request was made two weeks ago asking for exemption from the elements of the confidentiality agreement which the bank is able to grant in practice, he said.
Wilkinson was responsible for Danske Bank’s business operations in the Baltic region from 2007-2014.
He warned the bank of a number of potential irregularities in 2013 and 2014 before leaving his position.
He later acted as an anonymous whistleblower, helping Berlingske to uncover the major money laundering scandal at Danske Bank’s Tallinn branch, which is now being investigated by authorities in Denmark, Estonia, the United Kingdom and the United States.
After Estonian newspapers published his name, Wilkinson decided to make his identity public and will next week appear at hearings at both the Danish and EU parliaments.
