Interim Bolivian President Jeanine Anez was urged on Thursday to stand in May's presidential election, prompting a fellow right-wing candidate to brand such a move as unethical. Anez assumed the presidency on November 12 after leftist leader Evo Morales resigned following three weeks of sometimes violent protests against his controversial re-election in a poll the Organization of American States said was rigged. Morales' vice-president, and the presidents of the senate and lower house -- all members of the same Movement for Socialism (MAS) party -- likewise resigned, leaving Anez as the highest-ranking official. Anez was not a candidate in October's elections and has previously said she will not stand in the May 3 voting, either. Nationalist candidate Luis Fernando Camacho urged Anez to "stick to her word and for ethical reasons, not stand." Camacho was running third in a December opinion poll behind the leftist MAS candidate -- since announced as Luis Arce -- and centrist former president Carlos Mesa. But in another survey earlier this month, in which conservative Anez was included, she came in second with Camacho dropping to sixth. There are 10 days left for candidates to register. Anez has managed to bring stability to Bolivia, which suffered weeks of violent protests that left dozens dead. "The only way to save this country is for Jeanine Anez to be our candidate," Interior Minister Arturo Murillo told journalists on Thursday. Minister of the Presidency Yerko Nunez said Anez "instils peace and unity among all Bolivians." A centrist or right-wing candidate is expected to win an eventual June run-off should there be no outright winner in May's vote. But should Anez stand and further split the center-right vote, the chances of Arce winning would increase. jac/fj/dga/bc/dw
