Venezuelan opposition leader Juan Pablo Guanipa was released on Sunday after more than eight months in prison, he said in a video posted on social media.

Guanipa, one of the closest allies of the powerful opposition Maria Corina Machadohe was held in a detention facility in the capital, Caracas.

“We were released today,” Guanipa said in a video posted on X. “A lot to discuss about the present and the future of Venezuela, always with the truth in the foreground.”

He was detained at the end of May and charged by Minister of the Interior Diosdado Cabello for participating in an alleged “terrorist group” planning to boycott parliamentary elections that month. Guanipa’s brother Tomás denied the accusations and said the arrest was aimed at suppressing dissent.

“Thinking differently cannot be criminalized in Venezuela, and today Juan Pablo Guanipa is a prisoner of conscience of this regime,” Tomás Guanipa said after his arrest. “He has the right to think as he thinks, the right to defend his ideas and the right to be treated according to the constitution that is not implemented today.”

Juan Pablo Guanipa’s release comes amid mounting pressure on the government Acting President Delcy Rodríguez release all the people whose detentions a few months or years ago were linked by their families and non-governmental organizations to their political beliefs.

Rodríguez was sworn in as Venezuela’s acting president following the arrest of the then president Nicolas Maduro by the US military last month.

Her government announced last month that it would release a a significant number of prisoners — a central demand of the country’s opposition and US-backed human rights groups — but families and rights groups have criticized authorities for the slow pace of releases.
