Paraguayan President Fernando Lugo admits that he is the father of a child conceived while Lugo was still a Roman Catholic bishop.

Lugo surprised journalists Monday by acknowledging "with absolute honesty and transparency" that he had an intimate relationship with Viviana Carrillo, the child's mother.

Lugo promised to protect the privacy of the boy, and said he will not comment further on the matter.

The 57-year-old Lugo resigned as bishop of central San Pedro province in 2004. In December 2006, he announced that he was renouncing the status of bishop itself to run for president. But it was not until July 31 of last year that Pope Benedict XVI relieved him from his vows of chastity.

Carrillo's lawyer says the boy was born on May 4, 2007.
