Results of the unofficial referendum organized by Venezuela's opposition showed that 98.4 percent of the voters reject the formation of the National Constituent Assembly to change the Constitution.

He added that Maduro was elected president in 2013 with fewer votes than were cast in this consultation. "But these seven million people spoke, and it was plenty".
Venezuela is polarised between backers of President Nicolás Maduro and opponents, who want fresh elections.

Canada and Mexico were among the countries that issued statements Sunday evening lauding the opposition vote.

"If they're forcing us, it isn't democracy", Madriz said. Nearly all of the answers were related to the "yes" "He said when confirming the voters' rejection of the Constituent Assembly".

Maduro held his own rehearsal vote for the constituent assembly on Sunday, which may have dented turn out for the opposition's referendum as more than two million state workers were encouraged to attend.
