Brazil has declared Venezuela’s most senior diplomat in Brazil, Gerardo Delgado, as persona non grata.
The move came days after Venezuela’s decision to expel Brazil’s own ambassador to Caracas, Ruy Pereira.
Explaining its decision, Venezuela said Brazil had acted illegally in impeaching its former left-wing president, Dilma Rousseff.
On Saturday, Venezuela also expelled Canada’s charge d’affaires accusing him of interfering in internal affairs.
The head of Venezuela’s powerful Constituent Assembly, Delcy Rodriguez, said on Saturday that “diplomatic relations with Brazil will not be restored until the government reinstates the constitutional order it has effectively broken”.
Brazil and Canada have both become outspoken critics of President Nicolas Maduro. They accuse his socialist government of harassing the opposition and violating human rights.
