VATICAN CITY – The pope has accepted the resignation of a Colombian bishop accused by one of his priests of slander, the latest bishop to be removed after mismanagement or other accusations became public.

Bishop Carlos Prada Sanmiguel of Duitama-Sogamoso is two years shy of the normal retirement age for bishops. The Vatican said Monday he was resigning under the code of canon law that says bishops should step down if they’re sick or because a “grave” reason makes them unfit for office.

Colombian news reports have said Prada Sanmiguel claimed a priest had a relationship with a woman. The priest in turn accused the bishop of slander in a court case that is ongoing.

Last week the pope accepted the resignation of a Chilean bishop accused of sexually abusing a minor.
