France, Germany, UK, Switzerland , Netherlands, Belgium are a few I'm familiar with. There are of course areas of improvement, but in all of those you have strong press that can annihilate politicians for for crimes, as well as more or less working institutions that punish corruption.

Take a look at France, where a former president went to prison. Okay, it got commuted to house arrest (same sentence as a former PM candidate for president), but that's still a pretty serious punishment, especially for a such a high level politician.

There is no house arrest, he appealed and is innocent until proven guilty. People stay in prison after appealing in case there is a serious risk of them fleeing the country or in case they present a danger to society, both of these have been deemed low enough
