A SUMMARY OF THE SUPPORT FOR VENEZUELA'S RIVAL LEADERS, NICOLAS MADURO AND JUAN GUAIDO:
MADURO
* Defence Minister Vladimir Padrino reaffirmed his support in a tweet, saying Venezuela's armed forces disavowed any self-proclaimed president.
* The Supreme Court, stacked with Maduro loyalists, has remained solidly behind the socialist leader, ruling earlier this week that all actions taken by the congress - led by Guaido - are null and void.
* Russia called Maduro the country's legitimate president and accused the US of trying to usurp power in Venezuela, warning Washington against military intervention.
* President Tayyip Erdogan said Turkey stood by Maduro.
* China voiced support for Maduro, saying it opposed outside interference in Venezuela.
* State oil company PDVSA, which accounts for most of Venezuela's export earnings, stood by Maduro.
* A few left-leaning governments in the region, including Cuba and Bolivia, continue to back Maduro. Mexico said it will follow a policy of non-intervention.
* A diehard core of "Chavistas" in Venezuela, including armed gangs in poor urban areas, remain core to late leader Hugo Chavez's exhortation to support Maduro come what may.
GUAIDO
* The US recognised Guaido shortly after he proclaimed himself president, saying it would use its "economic and diplomatic power" to restore democracy in Venezuela.
* Numerous right-leaning Latin American governments, including Brazil, Colombia and Argentina, also recognised Guaido.
* The EU's executive called for new elections but declined to explicitly recognise Guaido as president. An EU statement urged authorities to respect his "civil rights, freedom and safety" and allow Venezuelans to freely determine their future.
* Spanish Prime Minister Pedro Sanchez told Guaido in a phone call he supported the legitimacy of the Venezuelan parliament and called for free elections.
* French President Emmanuel Macron saluted the courage of Venezuelans marching for freedom and called Maduro's 2018 election victory illegal.
* A spokesman for British Prime Minister Theresa May said Maduro's election was neither free nor fair, and expressed support for Guaido as national assembly head.
* The German government said Venezuela's parliament had "a special role" to play in securing Venezuela's "free future".
* There are some signs that support for the opposition is expanding beyond its traditional middle- and upper-class areas. Several protests against Maduro have broken out in working-class neighbourhoods and slums this week.
* Some low-ranking military officers have expressed discontent with the government.
