Uruguayan Alvaro Delgado, a 55-year-old former senator and the conservative ruling coalition's continuity candidate for president, is counting on support from an eliminated ally to triumph against the center-left frontrunner in Sunday's run-off election.

The presidential candidate of the conservative coalition that has governed Uruguay for the past five years conceded defeat on Sunday after a tight runoff election, as the South American nation joined others around the world in rebuking the incumbent party in a year of landmark elections.
