It's so funny because in the article it is even mentioned, that the agricultural minister did the same thing a few weeks ago, but he is from the chancellors party, the People's Party. Also, Nehammer (the chancellor) doesn't dissolve the government because his party is scared shitless of elections right now. They would (and in November at the general elections probably will) be painfully reduced. Sadly in favor of the super right wing FPÖ (fReEdOm party 🤡, as in freedom to be an asshole).
