An outspoken leader of Venezuela's opposition is being charged over what the government alleges was a US-backed plot to assassinate President Nicolas Maduro.
Venezuela's chief prosecutor yesterday ordered former congresswoman Maria Corina Machado to appear in court on December 3 to face charges.
What little is known about the alleged plot was presented in a highly publicised news conference in May following months of deadly anti-government protests.
At the time officials presented what they said were conspiratorial emails between Ms Machado, other prominent hardliners and US State Department officials, including Kevin Whitaker, the current US ambassador to Colombia, discussing funding and instruction for a plot to topple Mr Maduro's socialist government.
Arrest orders for three others implicated in the purported plot, all of them living abroad, were issued in June.
A cybersecurity forensics firm hired by one of the accused to clear his name determined the communications were fake.
Ms Machado was barred in June from leaving Venezuela just before being questioned in the case.
She denies any wrongdoing and said on Twitter that the charges are an attempt to silence her and others pushing for Mr Maduro to step down amid a gruelling economic crisis marked by the world's fastest inflation and widespread shortages.
Earlier yesterday, she presented a petition demanding the resignation of four government-aligned members of the National Electoral Council, which she accuses of gutting the public's faith in the country's voting system.
Ms Machado is one of Mr Maduro's fiercest adversaries and a divisive figure even within the Venezuelan opposition for having called for mass street protests in February, just two months after the government prevailed in mayoral elections.
After travelling to Washington in March to denounce Mr Maduro's government at the Organisation of American States, she was stripped of her seat in the National Assembly for allegedly committing treason.
