Both PAN and Morena condemned the brawl and traded accusations after a debate over a transparency oversight reform degenerated into a physical fight during a Mexico City legislative session, following widely circulated video showing lawmakers slapping, elbowing and yanking hair.The clash began when PAN deputies climbed onto the dais to halt debate on a proposal to dissolve the city’s Institute of Transparency and create a new oversight body, and Morena lawmakers moved to retake the podium as the melee lasted several minutes and attendees recorded the confrontation.PAN deputy Claudia Susana Pérez Romero required hospital treatment and a cervical orthopedic collar for neck trauma, the session was suspended, and the episode revived memories of an August Senate brawl between Alejandro Moreno and Gerardo Fernández Noroña that highlighted broader legislative tensions.
