The controversial vote comes amid protests that erupted in early April and have since claimed the lives of over 110 people. They followed an unsuccessful attempt of the Venezuelan Supreme Court to absorb the legislative power of the opposition-controlled parliament, the National Assembly.
On July 16, the country's opposition has held an unofficial referendum, in which 7.2 million people took part and almost 6.4 million of them voted against the Constituent Assembly. Venezuela's population is estimated at over 31 million people.
On Thursday, the Venezuelan government outlawed all protests ahead of a controversial election to the Constituent Assembly until next Tuesday. Still, many people have defied a ban on rallies and took to the streets on Friday night. At least one person died of a gunshot wound he sustained during clashes with law enforcement officers on Friday.
The United States warned it would sanction Venezuela and anyone who joins the new legislation body, if Maduro goes through with a July 30 vote.
