Gap. Proclaimed candidate lists are not on this page. The Central Electoral Board’s 2026 calendar sets presentation of candidacies for 21–26 October, proclamation for 2 November, and publication of the proclaimed lists in the Official State Gazette for 3 November. The candidacies section read on 17 October 2026 publishes forms and representative lists, not proclaimed Congress or Senate lists.

The electoral law regulates who may file a candidacy. This page does not summarise the requirements and does not explain how to file a list. The political-party register is kept by the Ministry of the Interior; the full register is not reprinted here.
