Baku-APA. Venezuela's opposition leaders say their signatures on a petition for a referendum to oust President Nicolas Maduro have been invalidated, APA reports quoting CNN.
Former presidential candidate Henrique Capriles is among those who say their signatures have been ruled out for "failing to meet the requirements".
The Speaker of the National Assembly, Henry Ramos Allup, described the move as "shameful" and "a provocation".
The decision was announced on Friday by the National Electoral Council (CNE).
The electoral body's president, Tibisay Lucena, said more than 600,000 signatures had been invalidated.
The other voters who signed the petition - more than 1.3 million people - will need to turn up at regional electoral offices to confirm their identity later this month.
Voters will have five days from 20 June to have their signatures checked.
