The next presidential term in Venezuela is set to begin Friday, when the ruling party-controlled congress will host a swearing-in ceremony for President Nicolás Maduro. That's despite serious doubts over the validity of last year’s official election results. Maduro is expected to begin a third six-year term amid demonstrations by his supporters, but it is unclear if anyone among the millions who voted for his main challenger, Edmundo González, will also protest. González, who claimed to have won the July election, left Venezuela for exile in Spain in September after a judge issued a warrant for his arrest.
