President Nicolás Maduro has won Venezuela"s presidential election, according to partial results published by the electoral council. The head of the National Electoral Council (CNE), Elvis Amoroso, who is a close ally of Maduro, said that with 80% of votes counted, President Maduro had 51.20% of the vote, compared to 44.02% for his main rival. The Venezuelan opposition has alleged widespread fraud in the counting of votes, and has vowed to challenge the result. It had united behind candidate Edmundo González in order to unseat Maduro after 11 years in power. Speaking to cheering supporters in Caracas, Maduro said his re-election was a "triumph of peace and stability". He praised the Venezuelan election system, describing it as transparent, and mocked the opposition, which he said "cries fraud" at every election. The US Secretary of State expressed his scepticism after the result was announced. Antony Blinken said the Unites States had "serious concerns that the declared outcome does not reflect the will or the votes of the Venezuelan people". Meanwhile, Cuba, a close ally of Maduro"s government, said that "the people spoke and the Revolution won". The opposition had deployed thousands of witnesses to polling stations across the country to be able to announce its own vote count. However, a spokeswoman for the coalition led by González said that their witnesses had been "forced to leave" at many polling stations. The opposition had also called on supporters to keep a vigil at voting centers to verify the counting process in the "decisive hours" after closing, amid widespread fears the government would attempt to steal the vote. Opinion polls had given González a wide lead over 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. — BBC
