Vanhanen and (then) Kuronen had a nine-month relationship after the Prime Minister and his wife Merja had announced their divorce in April 2005. After their romance ended, Kuronen frequently appeared in the media to talk about the relationship.
In February 2007 Kuronen published her tell-all book, in which she exposed intimate details about the romance and the Prime Minister’s private life. After the publication of the exposé, Vanhanen filed a complaint against its publisher Kari Ojala with the police, who investigated the case to see if charges could be filed.
Vanhanen himself announced on Friday on his web log that his complaint had led to charges and expressed satisfaction that there would be more clarity about “where the boundary of privacy runs”.
"I want to discuss the principle at stake here,” Vanhanen said to YLE News on Sunday. “Apparently some people think that the prime minister doesn't have the courage to go to court over this, and it seems that there are no limits to what is acceptable. Now we'll see whether these limits exist.”
Susan Ruusunen and her publisher have denied that they have broken the law by publishing the book. “Our defence will leave from the freedom of speech,” Ojala said in a reaction to Finnish newspaper Helsingin Sanomat. “Finns should surely continue to be able to write memoirs in which other people are mentioned.”
“But what do you do when there’s a sensitive-skinned Prime Minister,” the publisher added.
Susan Kuronen changed her last name to Ruusunen, the maidenname of her grand grandmother, earlier this year.
