A presidential run-off in the South American nation of Ecuador is shaping up as a referendum on the decade-long rule of leftist President Rafael Correa.

Under Correa the government has used oil revenues to slash poverty, but his ruling PAIS Alliance has been criticized for corruption scandals and a drift towards authoritarianism.

With term limits forcing Correa from office, polls show his chosen successor Lenin Moreno in a tight race with opposition candidate Guillermo Lasso.
