What could happen in Venezuela’s opposition primary?

Venezuela’s opposition will hold a primary on Sunday to pick its candidate for 2024 presidential elections, despite the front-runner being barred from holding office. President Nicolas Maduro is expected to seek another term.
The primary is the first the opposition has held in 11 years. It has not backed a presidential candidate in a general election since 2013.
The government and the opposition said in a joint agreement signed on Tuesday that each side can choose its candidate according to its own internal rules.
The primary could be a chance for the opposition to rally support from voters in Venezuela, whose economy has been in deep crisis for years.
The U.S. has long said it would lift some of its sanctions on Maduro’s government in exchange for democratic concessions from the president. Sources this week said Washington would consider some relief in response to Tuesday’s deal.
