Venezuela's opposition has called for the "largest movement that has ever existed" to oust President Nicolas Maduro, vowing to pursue all means to force him from power, including a referendum and protests.
The opposition Democratic Unity Roundtable coalition (MUD), which gained control of the legislature in December, spent weeks deciding on its strategy to remove the president, whose popularity has plunged in the face of a crippling economic crisis.
After heated debate over the merits of a referendum, a constitutional amendment or the drafting of a new constitution, the MUD announced its plan was all of the above, and more.
It placed special emphasis on its call for protests, starting from Saturday.
"The Democratic Unity Roundtable has taken the unanimous decision to call on the Venezuelan people to launch the largest popular pressure movement that has ever existed, to activate all - I repeat, all - mechanisms for change," said the opposition coalition's executive secretary, Jesus Torrealba.
That, he said, includes organising a recall referendum, which enables voters to remove elected officials midway through their terms - six years, in the case of the president.
Maduro was elected in 2013, a month after succeeding mentor Hugo Chavez following his death from cancer. Maduro reaches the midway point of his term in six weeks, on April 19.
To call a referendum, the opposition would need to get a petition signed by 20 percent of registered voters, or 3.9 million people, over a period of three days.
The referendum, to be organised within seven months, would then need to gather more votes than Maduro won with in 2013 - some 7.6 million.
A top Maduro ally, legislative minority leader Hector Rodriguez, said the president was ready for a "battle" and would not be pressured to resign.
"Nicolas isn't going to resign, he's going to dedicate himself entirely to governing for the majority of the country, including for them [his critics]," he told the AFP news agency.
Torrealba said the opposition will also use its legislative majority to draft a constitutional amendment reducing the presidential term.
An amendment would also have to win approval in a referendum.
Torrealba said the opposition will consider calling a constitutional assembly to draft a new constitution if the government continues its "irresponsible practice of trying to block the constitutional mechanisms for a peaceful solution to the crisis".
The opposition's landslide win in December's legislative elections is the biggest challenge yet to the "socialist revolution" movement that Chavez launched in 1999.
It comes against the backdrop of a deep economic morass exacerbated by the crash in the price of oil, which long funded Chavez and Maduro's lavish social spending.
Despite holding the world's largest crude reserves, Venezuela's economy contracted 5.7 percent last year, its second year of recession.

The crisis has stoked outrage in the South American country, where chronic shortages of basic goods, long lines and soaring prices have become the norm.
"We can't bear this anymore. We are the victims of the worst crisis in the country's history. Nothing works. That's why Venezuela has chosen the path of change," said Torrealba.
Political analysts say all the constitutional options to force Maduro from power face likely rejection by the Supreme Court or the National Electoral Council, both of which the opposition accuses the president of packing with allies.
The Supreme Court has struck down the opposition's powerful two-thirds majority in the National Assembly and dealt it a series of other blows.
"All these paths can be torpedoed by the constitutional chamber (of the Supreme Court), in an abusive exercise of its authority," constitutional law expert Jose Ignacio Hernandez told AFP.
