Guillermo Montenegro will return to the mayor's office of Mar del Plata due to the growing insecurity in the city.

Guillermo Montenegro (Jaime Olivos) Guillermo Montenegro has everything ready to return to the mayor's office of General Pueyrredón, whose main city is Mar del Plata, currently governed by Agustín Neme, who took office in December 2025 when Montenegro took a leave of absence to go to the Buenos Aires provincial Senate, a seat he won in the provincial elections, which were held separately from the national ones and featured many heavyweight names in the contest. According to what Infobae was able to learn, the politician will begin the process on Monday so that it can be addressed in Tuesday's session. There, as has happened on so many other occasions, the senator will request approval of his leave of absence, something he takes for granted. After that, the same process must take place in the Mar del Plata City Council so that his return is accepted. Given the political structure he has built, Montenegro will have no trouble achieving it. The reasons behind the decision are clear. The first is the growing insecurity affecting the entire province of Buenos Aires, but which in recent times has hit Mar del Plata, something that has made news in several local and national media outlets. Concerns about what is happening across Buenos Aires province have reached the national government, which at the last political strategy meeting included Minister Alejandra Monteoliva and said there was an "escalation in insecurity." The beach at Mar del Plata Guillermo Montenegro was Minister of Security for the city of Buenos Aires under Mauricio Macri and was strongly mentioned as a candidate to take over the national portfolio when Patricia Bullrich went to the Senate. However, that negotiation did not come to fruition. But the politician has experience in the field and acknowledges that he is the one who must take responsibility for what is happening, especially given his standing to coordinate tasks with federal forces. Recently, Mar del Plata experienced a string of criminal incidents that included home invasions, thefts of urban infrastructure, and episodes of violence. These incidents, which occurred in different neighborhoods and in different ways, reignited demands for security in the city. One of the most recent incidents was a home invasion in the Divino Rostro neighborhood. Five men with covered faces burst into a house on Matheu Street in the 1600 block, subdued the family, and escaped with nearly 20 million pesos, in addition to a sum in dollars. A gang accused of stealing underground cables at various points in Mar del Plata is also under investigation. Federal courts have accumulated more than ten complaints about an organization that came from the Buenos Aires Metropolitan Area (AMBA), operated in the early morning hours with cargo vehicles, generators, and clothing similar to that of a telephone company, and left the city within a few hours. The other reason is political, although everything is connected. The former prosecutor believes that if the insecurity situation continues to escalate, the risk of losing the mayor's office to Kirchnerism will grow along with it. Those close to him repeat that the model of the city built over all these years must be defended, and that the best way to do so is with Montenegro on the ground. Agustín Neme, current mayor In November 2025, the then-mayor of General Pueyrredón, Guillermo Montenegro, requested a leave of absence effective December 10 to assume the Buenos Aires provincial Senate seat he won in the provincial elections of September 7. Municipal leadership was left on an interim basis in the hands of councilman Agustín Neme, a leader he trusted. From the mayor's circle, it had been stated that the administration would maintain its direction and that it was not a definitive transition. The decision to request a leave of absence, rather than submit a resignation, left open the possibility that Montenegro would return to the mayor's office of Mar del Plata, something that will finally happen now. The politician had reached the provincial Senate after participating in the electoral alliance between PRO and La Libertad Avanza.
