Venezuela’s national election council has announced its approval of the first step in an opposition campaign to recall President Nicolas Maduro.
It said the opposition had succeeded in gathering 1% of voter signatures in all 24 of Venezuela’s states.
The move is the first part of the opposition’s push for an early end to President Maduro’s term in office.
In a further twist, the supreme court suspended opposition activity in the country’s parliament.
It said activity would be frozen until three opposition members being investigated for vote-buying were removed.
Venezuela is going through a political and economic crisis, which has led to shortages of basic goods and looting.
The inflation rate is one of the highest in the world and there are long queues outside shops.
The election council said Mr Maduro’s opponents had cleared the threshold of obtaining 200,000 valid signatures on a petition demanding that the president face a recall referendum.
The council did not set a date for the next stage of the lengthy recall process – when the opposition will need to collect four million signatures in just three days.
The opposition accuses Mr Maduro’s administration of mismanaging the economy.
Mr Maduro was elected in April 2013 and his term runs until 2019.
Correspondents say election council head Tibisay Lucena provided the president with a major fillip by stating that claims of widespread fraud in the opposition petition should be investigated.
Ms Lucena said the authorities had detected more than 1,000 apparently falsified signatures.
“The electoral authority will ask the state prosecutor’s office to investigate,” she said.
However she made clear that 98% out of about 408,000 signatures gathered by the opposition Democratic Unity (MUD) coalition – twice the minimum required in the initial phase – had been validated.
The government made clear that it was determined not to allow a referendum this year.
It has initiated nearly 9,000 lawsuits around the country in an effort to try to halt the referendum push.
Correspondents say timing is vital because if President Maduro loses a referendum this year – as polls suggest he will – a new presidential vote will be triggered, giving the opposition a chance to end 17 years of socialist rule.
But if the president loses a referendum next year, he would be replaced by his vice-president, effectively ensuring the socialist party remain in power until the next presidential election scheduled for 2018.
Opposition leaders want Ms Lucena immediately to announce a date for the collection of 20% of signatures in order to trigger a referendum as soon as possible.
