A debate between lawmakers in Mexico City erupted into chaos on Monday, with members of both parties clashing, leading to shouting, shoving and hair-pulling.

Lawmakers from the opposition National Action Party took the congressional podium to protest the dissolution of Mexico City’s transparency institute and the transfer of its functions to a government agency.

The opposition bloc accused the ruling party, Morena, of not respecting an agreement to make the new transparency body tripartite, leading to the podium occupation.
