Wever government: What is “Kern”, this “all Belgian” peculiarity?

In the piloting post of this government is what is called the Kern, composed of the Prime Minister and five vice-prime ministers. What is his role and who composes it?
What does the term “Kern” mean? In Flemish, that means “Kernkabinet” and, in French, a limited ministerial committee. This is a Belgian specificity which, unlike the councils of ministers, is not based on any legal basis. However, it is within this body that essential decisions are played out.
Around the table is the Prime Minister Bart de Wever and a representative of each party of the government coalition. For the commitments, Maxime Prévot, Minister of Foreign Affairs. For the reforming party, David Clarinval, Minister of the Economy. On the Dutch -speaking side, there are Jan Jambon, Flemish nationalist and Minister of Finance, alongside Franck Van Den Broeck, Flemish socialist and Minister of Health, as well as Vincent Van Peteghem, Minister of Budget. There are no women around the table.
It is they, the Deputy Prime Ministers who will decide and arbitrate the main orientations of the government led by Bart de Wever. These are people who know each other well. They have negotiated the government agreement for weeks, this famous Arizona government.
Is this an experienced Kern to direct the country?
It all depends on the political journey of each. Frank Vandenbroucke, undoubtedly the most experienced with 30 years of career, was already Vice-Prime Minister under the Dehaene government in 1994 and returns to health today after having known everything. Jan Jambon, with 10 years of experience, began his career in government as vice-president during the Michel government in 2014. David Clarinval, on the other hand, arrived under the Wilmès government in 2019, Minister. And then then Deputy Prime Minister during the following government. Just like Vincent Van Peteghem, 5 years of experience. He arrived under the government of Croo directly as Deputy Prime Minister.
Two exceptions are distinguished: Maxime Prévot, although being a novice at the federal level, occupies a strategic position as a party president. And then he was vice-president of the Walloon government. There is also obviously Bart de Wever, also a novice to the federally. This is a first. But he has been president of the N-VA for 20 years. A strategic position. And above all, he is Prime Minister, above all. The chief of Kern is him.
