Susana Laciar, allied to Together for Change, will be the first mayor of the provincial capital. On Sunday he prevailed over Emilio Baistrocchi, the governor's dauphin who was seeking re-election.

For the first time in history, the city of San Juan will have a woman as mayor as of December 10. Laciar was a provincial deputy and vice presidential candidate for Marcelo Orrego in his previous candidacy. The lawyer, 54, separated and remarried in second marriage.
