Carles Puigdemont, the former president of Catalonia, has announced his return to Spain to attend the investiture debate of Salvador Illa, scheduled for Thursday.

This move has prompted the Mossos d'Esquadra, Catalonia's police force, to prepare a significant security operation to prevent Puigdemont from entering the Catalan Parliament.

Despite an offer for a discreet arrest, Puigdemont's lawyer rejected the proposal, leading to heightened tensions.

Supporters of Puigdemont plan to gather at the Lluís Companys promenade to welcome him, while opposition party Vox has organized a protest against his return.

The police will close off the Ciutadella Park, where the Parliament is located, to manage potential crowds and ensure order during this politically charged event.
