2024 Belgian government formation

Following the 2024 Belgian federal and regional elections, Government formation talks began on 10 June. Incumbent Prime Minister Alexander De Croo has announced his resignation and his party's leader Tom Ongena has declared that Open Flemish Liberals and Democrats would not be a part of the next federal government.

According to political analysts, the most obvious federal coalition would consist of the right-wing New Flemish Alliance, Reformist Movement, and centre-left Vooruit, with the centrist Christian Democratic and Flemish and Les Engagés parties to reach at least 76 seats. Other coalitions are ruled out, following the decision of Open Vld, Groen and the Socialist Party to be part of the opposition. Vlaams Belang is not expected to be part of the government at any level, due to the cordon sanitaire.

On 12 June, after consulting with party presidents, King Philippe named N-VA leader Bart De Wever as informateur. He had to submit a report by 19 June. After said report was submitted, his mission as informateur was extended by another week until 26 June.

On 15 June, Melissa Depraetere, leader of Vooruit, declared that she didn't wish Georges-Louis Bouchez, leader of MR, to be in the future government, citing his "disloyal" attitude towards the De Croo Government and his lack of proficiency in Dutch as factors that would harm a future coalition. She also declared that she desired to push a social design onto a future coalition that she notes is emerging to be on the right, which, in her eyes, will make negotiation very difficult.

On 21 June, Bart De Wever announce that he sees the only logical government formation to be the so-called "Arizona coalition" (N-VA - MR - LE - Vooruit - CD&V), which combines the respective parties negotiating in Flanders and Wallonia for the respective regional governments. According to De Wever, any other attempt at government formation would lead to a period of endless negotiations. He specifies that the Arizona formation would allow for relative coherence on a socio-economic level, but that it would make any prospect of institutional reform more difficult to negotiate..

Possible coalitions

Sorted descending by number of total seats:

Coalition	Coalition parties		Total number of seats	Flemish seats	Francophone seats	Pitfalls
	Flemish	Francophone
Vivaldi incl. LE	Vooruit +   CD&V +   Open Vld +   Groen	MR +   PS +   LE +   Ecolo	90 / 150	37 / 89	53 / 61	Extension of the outgoing coalition strengthened by LE. Broad coalition which is a minority on Flemish side. Open Vld and PS both decided to remain in opposition. PS needed for majority.
Arizona excl. PS & Open Vld	N-VA +   Vooruit +   CD&V	MR +   LE	82 / 150	48 / 89	34 / 61	Vast political differences in opinion between largest (N-VA) and second largest (Vooruit) Flemish parties. Vooruit president Melissa Depraetere has stated that her party may refuse to be part of a government including MR president George-Louis Bouchez, citing issues with his "disloyalty" to the incumbent Vivaldi government.

Other coalitions are also mathematically possible, but in practice unlikely. For instance: both the PS and Open Vld had announced in the beginning of the formation that they preferred to remain in the opposition, while extremist parties on both sides (left: Workers' Party of Belgium, right: Vlaams Belang) are unlikely to be part of the government due to vetoes by other parties.
