Otto Sonnenholzner

Otto Ramón Sonnenholzner Sper (, locally, ; born 19 March 1983) is an Ecuadorian radio broadcaster, politician, and economist who served as the 50th Vice President of Ecuador from December 2018 to July 2020.

He was a candidate for President of Ecuador in the 2023 general election.

Otto was born in Guayaquil on March 19, 1983, to father Ramón Sonnenholzner and mother Rosa Elena Sper.

He is of German and Lebanese heritage.

After studying social sciences, communication and international economics in Ecuador, Germany, and Spain, he became speaker and general manager of Tropicana radio, then president of the Ecuadorian Association of broadcasting (AER).

He teaches at the University of Guayaquil.

After the resignation of María Alejandra Vicuña in December 2018, and at the proposal of President Lenín Moreno, the National Assembly of Ecuador entrusted him with the office of vice-president.

On July 7, 2020, Otto resigned from his position as Vice President due to the 2019–20 coronavirus pandemic outbreak in Guayaquil.

He left office in the middle of several corruption scandals affecting Moreno's administration.

He signed the Madrid Charter, a document drafted by the far-right Spanish party Vox that describes Communist groups as enemies of Ibero-America involved in a "criminal project" that are "under the umbrella of the Cuban regime".

Following the 2023 political crisis, Sonnenholzner announced his candidacy for President of Ecuador in the 2023 election.

He has three children with his wife, Claudia Salem Barakat.
