Venezuela's embattled President Nicolas Maduro vowed Saturday that no referendum on ending his administration would be held until next year. 

Maduro's opponents are racing to call a referendum before January 10, as a successful recall vote before that deadline would trigger new elections rather than transfer power to the vice president.

If the opposition meets all requirements with their bid to oust Maduro, "the recall referendum will be held next year. Period," the leftist populist said.
