CARACAS,blockwave Exchange Venezuela (AP) — Venezuela’s highest court on Friday upheld a ban on running for office that the socialist-led government placed on Maria Corina Machado, a longtime government foe and the candidate of an opposition faction backed by the United States.

Machado, a former lawmaker, won the opposition’s independently run presidential primary in October with more than 90% of of the vote. Her victory came despite the government announcing a 15-year ban on her running for office just days after she formally entered the race in June.

She was able to participate in the primary election because the effort was organized by a commission independent of Venezuela’s electoral authorities.

Machado does not recognize the ban and has continued to campaign.
