A brief statement on KAPO's website on December 20 only tested the origin of the claims, saying the information was likely provided to the press by unofficial sources, and that therefore a state secret has not been infringed.

Last week, Savisaar contacted the public prosecutor's office, saying the leaking was a crime. He also said that the information was "obviously" leaked by one of the four officials who allegedly received the intelligence briefing in question. "The problem is with those senior government officials who leak secret information, evidently knowing that the information was not true," said Savisaar. 

Before a complete explanation can be given, KAPO said it must first brief the government security commission, which includes the Prime Minister, as well as the defense, foreign, interior, justice and finance ministries. Earlier in the day, the Prime Minister already called for KAPO to unveil the facts, calling Savisaar's actions "disgusting."  

With a strong ethnic Russian following, Savisaar has admitted to receiving money ahead of elections to build a Russian Orthodox church. A few weeks before the parliamentary elections, the cross blessing ceremony will take place at the church that was built with 1.5 million euros attained by Savisaar.

Critics, including European Commission Vice President Siim Kallas (also the founder and a continuing member of the Reform Party) told Postimees that the EU norm is to reject foreign funds for boosting election campaigns. "Within democratic European countries, elections are a domestic process," said Kallas. 

The high-profile donator is Vladimir Yakunin, a former KGB officer, a close friend of Russian prime minister Vladimir Putin. Director of the state-owned Russian Railways, Yakunin tends to stay out of public attention; however, the New York Times called him a potential candidate in Russia's 2008 presidential elections.

"If Putin picks a successor, that person will probably likely be drawn from a circle of close associates with whom he has a long history of personal relations. At the same time, the candidate will need to have enough personal charisma to run for the presidency and ensure victory in the elections. There are at least four figures who fall into this category," the New York Times wrote of him in 2007.
