The European lawmakers also waived immunity for former Catalan health minister Toni Comin and former regional education minister Clara Ponsati.
The trio fled to Belgium in October 2017 along with other Catalan separatists. They are wanted by Spain after holding an independence referendum that the Spanish government said was illegal.
In 2019, Puigdemont, Comin and Ponsati won seats in the European Parliament. This gave them protection in their positions as members of the EU assembly.
But last month, the parliament's Legal Affairs Committee voted to recommend waiving their immunity. /BGNES
