Ex-bishop takes on ruling party

A former Roman Catholic bishop could end more than 60 years of one-party rule in Paraguay's closely fought presidential election on Sunday and join the growing ranks of leftist leaders in Latin America.

Fernando Lugo left the priesthood to seek the presidency as the head of a center-left coalition. Most polls show him with a slim advantage over the ruling Colorado Party candidate, Blanca Ovelar, and retired army general Lino Oviedo.

The vote will be a referendum on the world's longest-ruling party still in power.
