Protests seen around country after results appear to dash opposition hopes of ending quarter century of chavista rule

• ‘We are longing for change’: Venezuela election sparks pots and pans protest

Nicolás Maduro’s claim of victory in Venezuela’s presidential election has brought the South American country to a hazardous standoff, with his thwarted opponents accusing him of rigging the election to remain in power, and many leaders in the region and beyond questioning the veracity and transparency of the vote.

Late on Monday, street protests were reported across the capital and all around the country, including in the states of Falcón, where demonstrators were filmed tearing down a statue of Hugo Chávez, and Portuguesa, where footage showed a group vandalizing a propaganda billboard featuring a photograph of Maduro and a slogan promising “More Changes and Transformation”.

Washington says it has ‘serious concerns’ about result, while president of Uruguay says it is open secret Maduro would win ‘whatever real results were’

Among the many international figures weighing in on the situation in Venezuela was the US vice president, Kamala Harris.

“The will of the Venezuelan people must be respected. Despite the many challenges, we will continue to work toward a more democratic, prosperous, and secure future for the people of Venezuela,” she said.

More than a thousand international observers have taken part in the Venezuelan election. The people have spoken and their will should be respected. The right only goes along with democracy when it wins and that is unacceptable.

Nicolás Maduro’s apparent re-election as Venezuela’s president has been met with scepticism, suspicion and calls for a transparent and detailed breakdown of the vote in Sunday’s controversial poll.

Nicolás Maduro has been declared the winner of Venezuela’s presidential election by the government-controlled electoral authority – a result that appeared to dash opposition hopes of ending his authoritarian, socialist rule. It was immediately challenged by rivals and several governments in the region and beyond.

After a six-hour delay in releasing the results of Sunday’s poll prompted international concern, Venezuela’s electoral council claimed Maduro had won with 51.21% of votes compared with 44.2% for his rival, the former diplomat Edmundo González Urrutia.
