Pope Francis accepted the resignation of Cardinal Robert Sarah as head of the Vatican's office for liturgy, removing an outspoken conservative and possible future pope from the ranks of Vatican leadership.

The Holy See Press Office announced Saturday that Cardinal Sarah had stepped down. No successor has been named.

The cardinal submitted his resignation as required by church law when he turned 75 on June 15 of last year. But the pope frequently lets cardinals serve two or three years past that age, though not past 80. Last June, the cardinal wrote on Twitter: "For my part, I am happy to continue my work" at the Vatican.
