The Finnish government is investigating how a confidential e-mail exchange on European sanctions against Russia was leaked to local media.
Prime Minister Alexander Stubb’s office said on Tuesday it is looking into the breach, which was detected late last week.
“Last Friday we discovered that some of these e-mails had been offered to media for publication,” Markku Mantila, a spokesman for the government in Helsinki, said in a phone interview. “But I haven’t seen any of these e-mails published.”
The suspected leak covers the term of Stubb’s predecessor, Jyrki Katainen, Lauri Tierala, special adviser to the prime minister, said on his Twitter account. Stubb became premier in June last year, after Katainen left for a post in the European Commission.
The leaked e-mail exchanges were between the prime minister and Finnish civil servants, Mantila said. He said he couldn’t confirm whether any of the messages were sent to recipients outside the country.
The Finnish government said in February that the European Union is considering tightening sanctions against Russia, a stance the Nordic country said it backed.
The Finance Ministry in Helsinki is still waiting for the police to provide the findings of a probe into a leak, in which excerpts of a memo on Greece were published by the newspaper Helsingin Sanomat last week.
