Why did Finland's ranking of incorruptibility drop?

In the past year, there has been controversy about the source of campaign funds. Many companies and interest groups provide funds to political parties through various forms to help them campaign, which affects the formulation and implementation of policies. At first, problems were found in local elections, and later, the same problems were found in parliamentary elections. Several major political parties were involved in scandals to varying degrees.

In addition, the hottest issue recently is the Prime Minister's Office. Finnish national television program said that when the Prime Minister built the house, some materials were misappropriated by the construction company from other places, and the Prime Minister did not pay for it. The prime minister denied the accusation, and the TV station said it wanted to protect the informant and was unwilling to provide more evidence. The police station said that it happened more than ten years ago, and the amount was not large enough to be worth investigating. So I still don't know what's going on

The former foreign minister was also exposed, and his 60th birthday was paid for by "friends". Earlier, he was exposed to having an affair with a stripper. Finally resigned as foreign minister.

Finnish scholars have done research, saying that corruption in Finland is an exchange of interests through collusion within elite groups, and it is corruption that basically does not see money and leaves no handle. At the bottom, corruption is really less. For example, if the police catch you speeding or drunk driving, you can't get away with it by stuffing some money.
