The debate over state secularism remains a contentious issue, with Démocrate Fédéral seeking constitutional recognition while Les Engagés prefer the term 'neutrality'.

In addition to secularism, the two parties also diverge on abortion laws, as Démocrate Fédéral advocates for extending the legal limit to 18 weeks, whereas Les Engagés previously supported a limit of 14 weeks.

Historically, Démocrate Fédéral has maintained three 'red lines' that have complicated cooperation: a refusal to join a government with N-VA, a strong emphasis on state secularism, and differing views on abortion legislation.

Jean-Luc Crucke, an Engaged deputy, expressed support for a merger but noted that the immediate priority lies in coalition negotiations related to the Arizona coalition.

Georges Dallemagne, a former Engaged deputy, highlighted the necessity for unity among centrist parties to effectively tackle pressing issues such as the future of the European Union and national security.

The recent departure of Olivier Maingain from Démocrate Fédéral (Démocrates) has reignited discussions about a potential alliance with Les Engagés, aiming to form a significant centrist coalition in Belgium.

This shift comes as Démocrate Fédéral adopts a more conciliatory approach towards the New Flemish Alliance (N-VA), suggesting a possible opening for dialogue between the two parties.

Maxime Prévot, president of Les Engagés, acknowledged that past opportunities for collaboration were missed by Démocrate Fédéral, but emphasized the importance of timing and mutual respect in future discussions.

Dallemagne also suggested that Maingain's departure could facilitate negotiations that had previously stalled in early 2023.
