Flemish PM Diependaele Urges Switch from CM Health Fund in Pillar System Clash

Flemish Minister-President Matthias Diependaele (N-VA) has launched an extraordinary frontal attack on Belgium’s largest health insurance fund, the Christian Mutuality (CM), urging its members to switch to a rival provider. Speaking at a party event in Ninove alongside N-VA chair Valerie Van Peel, Diependaele described CM as “the association that does nothing but sit on our backs” and called on members to move to the Flemish & Neutral Health Insurance Fund (VNZ) — a smaller, Flemish-oriented competitor.

Background: The Pillar System Under Fire

The remarks, reported by Het Laatste Nieuws, mark the latest escalation in a months-long N-VA offensive against Belgium’s entrenched “pillar” system (verzuiling) — the network of ideological organizations including health insurance funds, labor unions, and civil society groups that have historically been tied to political parties. CM, linked to the Christian democratic CD&V party, is Belgium’s largest health insurance fund with millions of members.

Diependaele’s call to switch is notably direct for a sitting minister-president. “I sat with Jürgen Constandt, the head of the Flemish & Neutral Health Insurance Fund (VNZ), this afternoon,” he said. “It’s time to switch, dear people. Urgently time.” He added that VNZ “stands for the same values and norms and especially for a strong Flanders.”

Coalition Tensions Exposed

Van Peel went further, explicitly criticizing coalition partners Vooruit (socialist) and CD&V (Christian democrat) for being beholden to their respective pillar organizations. According to De Standaard, she stated: “Conner (Vooruit chair Rousseau) has to ask his party board whether ABVV chair Bert Engelaar approves. And Sammy (CD&V chair Mahdi) has on one hand his Boerenbond… and on the other hand CM chair Luc Van Gorp. Those parties can’t make that kind of honest analysis.”

These unusually blunt remarks highlight growing strains within Belgium’s coalition government, where N-VA governs alongside parties with deep historical ties to the very organizations it now attacks.

A History of Escalation

The clash is not new. In April 2026, Van Peel’s proposals to reform long-term sick leave oversight — suggesting control doctors should not depend on health insurance funds — sparked a furious reaction from CM chair Luc Van Gorp. VRT NWS reported Van Gorp calling the proposals “patently untrue” and “immoral.” In May, Van Gorp further accused politicians of engaging in “dangerous framing on the backs of the most vulnerable,” as reported by HLN.

Analysis: Strategy or Ideology?

Political scientist Stefaan Walgrave of the University of Antwerp, speaking to VRT NWS, noted that the N-VA’s motivations are difficult to parse. The party’s push for the “primacy of politics” — where elected officials hold decision-making power over unelected intermediary organizations — has ideological roots but also practical fiscal implications. Walgrave warned that delegitimizing all intermediary organizations can be dangerous, citing Hungary under Orbán as a cautionary example.

Sociologist Luc Huyse of KU Leuven explained that pillarization was historically a mechanism to manage ideological conflicts in Belgian society, but that since the 1960s, these organizations have transformed into more political entities focused on organizational survival.

What’s Next

CM has not yet issued an official response to Diependaele’s latest remarks, but the organization has been increasingly defensive in recent months. The confrontation raises several open questions: Will CM members actually switch providers in response to the minister-president’s call? Can the coalition government withstand these internal tensions on healthcare reform? And is the N-VA planning concrete legislative action to dismantle or restructure the health insurance fund system?

For now, Belgium’s centuries-old pillar system faces its most direct political challenge in decades — with the Flemish government’s own leader actively campaigning for members to abandon one of its core institutions.
