Venezuela's opposition has called for a 24-hour strike on Thursday in protest against President Nicol's Maduro's plans for a new constituent assembly. <br/><br/>In a statement, leaders said 7.6 million people had taken part in Sunday's opposition-organised referendum on the plans. They also announced they would name new Supreme Court judges. <br/><br/>The assembly, made up of citizens, would have power to scrap the National Assembly and rewrite the constitution. Opposition parties control the National Assembly and are calling for fresh elections before Mr Maduro's term expires in early 2019.
