Carles Puigdemont, the former president of Catalonia, is set to return to Spain for the investiture of Salvador Illa, raising tensions ahead of the parliamentary session.

Puigdemont, who has been in self-imposed exile since 2017, faces an active arrest warrant for embezzlement.

The Catalan police, Mossos d'Esquadra, are preparing a security plan to prevent his access to the Parliament, where his potential arrest could disrupt the investiture process.

While Puigdemont's party, Junts, seeks to delay the vote if he is detained, ERC and the Comuns are advocating for a temporary suspension of the session, emphasizing the need to resume quickly.

The political landscape remains volatile as the deadline for a new president looms, with elections possible if no agreement is reached by August 26.
