A leading Peruvian newspaper says it will no longer publish columns by Roman Catholic Cardinal Luis Cipriani after he was caught plagiarizing two popes.

The unattributed texts were found last week in two columns that El Comercio published, one earlier this month the other in May.

They were discovered by reporters at the news website Utero.pe, which determined that Peru's cardinal had lifted texts from Paul VI and Benedict XVI.

El Comercio ratified the findings Friday, saying on its website that Cipriani had penned his last column for the paper. It deleted the two columns from its website.

The conservative 71-year-old cardinal apologized Saturday on a radio program and asked listeners to "pray that we pastors are always true to the teachings of the church."
