Martín Insaurralde

Since 2021, he has served as Chief of the Cabinet of Ministers of Buenos Aires Province, under Governor Axel Kicillof.

On 19 September 2021, Insaurralde was tapped as the new Chief of the Cabinet of Ministers of Buenos Aires Province, under Governor Axel Kicillof. He replaced Carlos Bianco as part of a cabinet reshuffle following the governing Frente de Todos' defeat in the 2021 primary elections.

On 12 June 2020, during the COVID-19 pandemic, Insaurralde announced that he had tested positive for the virus, and urged people to stay home to protect themselves. He had recently been in contact with Argentine president Alberto Fernández, who later went into voluntary self-isolation. After nearly two weeks in hospital, as well as receiving a blood transfusion, he was cleared to return to his home on 24 June.

In April 2019, Insaurralde launched "Eco Lomas", a programme with an aim of caring for the environment in Lomas de Zamora, and heading for "a greener city with a better quality of life". As part of this programme, nine new recycling centres were built across the municipality, and a scheme was set up to provide school pupils with bicycles to incentivise physical activity.

His father, Rodolfo Insaurralde, died in 2017. He was more than 80 years old at the time of his death.

Insaurralde resigned his post as a member of the Chamber of Deputies to return as a candidate for mayor of Lomas de Zamora in the 2015 Argentine general election. He was replaced in the Chamber of Deputies by Luis Cigogna.

Insaurralde was re-elected in the October 2015 elections with 47.53% of the vote, against the 26.31% of his closest rival, Gabriel Mercuri of Cambiemos. During the 2019 Argentine general election his mandate was re-confirmed, obtaining 59.16% of the vote, against 30.13% obtained by the Together for Change candidate, who was closest.

He remained in the role of mayor until 2013, at which point he resigned to become a member of the Chamber of Deputies. He was replaced by Santiago Carasatorre.

On 22 June 2013, Martín Insaurralde was confirmed as the first list candidate for member of the Chamber of Deputies, on the Buenos Aires province list of the Front for Victory for the August primary elections. Days later, on 26 June, the list he headed received support from the mayors of 78 municipalities of Buenos Aires, and from the governor of the province, Daniel Scioli.

In the primary elections of 11 August 2013, Insaurralde's list gained 29.65% of the vote, putting the list in second place behind the Renewal Front of the mayor of Tigre Partido Sergio Massa, which gained 35.05%. He subsequently spoke of his conviction that this result could be overturned by the time of the legislative elections on 27 October. During these elections, the Front for Victory list gained a greater percentage of the vote - 32.18% - but still remained roughly the same distance behind the Renewal Front, who won the elections with 43.92% of the vote.

After two years of being a caretaker mayor of Lomas de Zamora, Insaurralde was elected in the 2011 Argentine general election with 66.16% of the vote, against the 8.24% gained by the Broad Progressive Front candidate; this was the highest percentage in the history of local elections in the partido. Insaurralde also won the primary elections in August 2011 with a large margin, obtaining 62.73% of the vote, against 10.2% for the nearest candidate from the Popular Union.

During the 2011 election campaign, Insaurralde announced that he had been diagnosed with a seminoma, a type of testicular cancer. He went through surgical treatment for the cancer, and treatment including chemotherapy. On 10 September 2011, he said that the experience was "one of the most difficult" of his life, and that without the "company" of his constituents, it would have been more difficult.

On 27 October 2009, Rossi resigned his post for personal reasons, and Insaurralde replaced him as a caretaker mayor, as a consequence of his being the top of the electoral list, and so the first in the line of succession.

In 2003, Martín Insaurralde was elected as a councillor in the municipal council of Lomas de Zamora, under the electoral list led by Jorge Rossi as mayor. In the 2007 elections he was re-elected as a councillor under the banner of the Front for Victory, with 17% of the vote.

In 1993, Insaurralde married Liliana Toledo, with whom he had two children, Martín and Rodrigo; they divorced in 2000. In 2005, he married Carolina Álvarez, with whom he had a third child, Bautista; Insaurralde and Carolina also divorced, three years later. In November 2014, Insaurralde married the actress and model Jésica Cirio, with whom he had another child, Chloé.
