I'm from Slovenia and it is very obvious what is going on behind the scenes. It's a public secret at this point that both the parties in charge (especially the people in/around Gibanje Svoboda) and the various people "from behind" take their cuts at big infrastructure projects.

Just to be fair, this is not unique to the current government. We've had several similar corruption scandals throughout several governments; it was almost always related to infrastructure projects.

A few days prior to this leak there was a separate one posted on Facebook (that I sadly can't find anymore; it has been covered by several media outlets here [1]), in which the former GS secretary reveals who gets what % and that they have to "set our own people to the right places, as (2023) floods cleanup is where the most money flows".

It is also not a secret that the mayor of Ljubljana, Janković, is able to bypass all laws to issue building permits in exchange for a 20% "donation" to city-ran sports clubs, which are ran by his friends. This was revealed in the case of an Austrian investor and his luxury flats at Celovška cesta, Ljubljana, a few months ago.

It's also plain obvious that the state media (RTV SLO) is trying hard to shift the conversation towards the origin of the leaks rather than the supposed corruption revealed in them. The practice had usually been to investigate the content first.
