Venezuelan opposition leader María Corina Machado will not attend the Nobel Peace Prize ceremony in Oslo on Wednesday, the Norwegian Nobel Institute said, with her daughter receiving the award on her behalf.

Machado, who has not appeared in public for 11 months, was briefly detained last January after participating in a protest in Caracas. Nobel Institute director Kristian Berg Harpviken said the Venezuelan leader was expected in Oslo but “unfortunately, she won’t arrive in time to attend today’s ceremony or other events.”

Machado’s spokesperson, Claudia Macero, confirmed she will miss the ceremony but hoped she could join other events scheduled later in the day. Her current location was not disclosed.

Several prominent Latin American leaders, including Argentine President Javier Milei, Ecuadorian President Daniel Noboa, Panamanian President José Raúl Mulino, and Paraguayan President Santiago Peña, attended the ceremony to show solidarity with Machado.

The 58-year-old won the Nobel Peace Prize for her efforts to push for a democratic transition in Venezuela. She had previously won an opposition primary to challenge President Nicolás Maduro in last year’s presidential election, but was barred from running. Her replacement, retired diplomat Edmundo González, later sought asylum in Spain amid a government crackdown.

Human rights groups and U.N. officials have repeatedly expressed concern over the situation in Venezuela, citing arrests, disqualifications, and repression of dissent. Nobel officials noted that it is customary for family members to represent laureates unable to attend, citing past winners who were imprisoned, including Narges Mohammadi of Iran in 2023 and Ales Bialiatski of Belarus in 2022.

Venezuelan human rights activist Gustavo Tovar-Arroyo said supporters had done their best to bring Machado to Oslo, but warned that such risks are part of challenging a dictatorship.
