Viktor Klima was never a president in Austria, he was Chancelor. President back then was Thomas Klestil.
And the situation was different, there was a realistic chance for the SPÖ to form a government, as they had a majority together with their former coalition partner (who rather made a goverment with the radical-right then)
In Poland, PiS has no chance whatsoever to form a government, as three opposition parties have a majority and publicly stated that they will form a government together. So, its just Duda giving his buddies another month to be corrupt and hide/cleanup what they have done.
I think that refers to Portugal being ruled by the Socialist party for 8 years
