(2 Aug 2017) The turnout figures in Venezuela's Constituent Assembly election were "tampered with", the director of a company that provides electoral support services to the country said on Tuesday.
Speaking in London, Antonio Mugica, the CEO and Director of Smartmatic, said the company estimated "the difference between the actual participation and the one announced by the authorities is at least one million votes"
Smartmatic was a company created by Venezuelans in Caracas providing electronic voting machines to the late President Hugo Chavez. In recent years it has branched out to provide the same services to countries across the world, while continuing to provide support for elections in Venezuela.
Venezuelan President Nicolas Maduro called the vote for the constitutional assembly in May after weeks of protests fed by anger at his government over food shortages, triple-digit inflation and high crime.
Many people accuse the ruling party of corruption and mismanagement.
