Bolivia’s conservative interim president, Jeanine Anez, pulled out of next month’s general election on Thursday, a move that should strengthen other candidates running against the front-running socialist party of ex-leader Evo Morales.

Anez said in a video message she sought to unify those opposing the candidate for the party of Morales, who resigned last year after an election sparked widespread protests. Anez, a former senator, took office in the power vacuum that followed Morales’ departure.
