Venezuela election: Maduro declared winner in disputed vote

Opinion polls had given Mr González a wide lead over Mr Maduro.

Many voters said that they wanted change after 25 years in which the socialist PSUV party has been in power - first under the leadership of the late President Hugo Chávez, and after his death from cancer in 2013, under Nicolás Maduro.

Under their leadership, the PSUV has gained control not just of the executive and the legislative, but also of much of the judiciary.

The last election in 2018 was widely dismissed as neither free nor fair and there had been widespread fear in the run-up to this election that the poll could also be beset by irregularities.

Those fears were further stoked by President Maduro, who said he would win "by hook or by crook".

The opposition nevertheless struck a positive note going into the election, arguing that if their supporters turned out en masse, it would make it very hard for the government to "steal the election".

Voting in Venezuela is electronic. Voters punch in a button assigned to their preferred candidate on a voting machine.

The electronic results are sent to the CNE headquarters, but the machine also prints out a paper receipt which is then placed in a ballot box.

By law, parties are allowed to send witnesses to the count of these paper receipts carried out at each polling station, but many were prevented from doing so.

The opposition said it had been given access to less than a third of the printed receipts.

Their plan had been to monitor these tallies to see if they squared with the results announced by the CNE.
