Lawmaker Luis Parra, candidate for President of the National Assembly, arrives for a session at the National Assembly, in Caracas, Venezuela. Venezuela's opposition leader Juan Guaido lost his seat as the president of the National Assembly to Luis Parra in a Sunday vote. Guaido, who proclaimed himself Venezuela's interim president in a failed attempt to oust legitimate head of state Nicolas Maduro a year ago, did not take part in the voting session.
