Archbishop Georg Gänswein, Prefect of the papal household and personal secretary to Benedict XVI, has been hospitalised with "severe kidney problems". German-language Catholic news agency CNA Deutsch reports that the 64-year-old has been admitted to hospital in Rome. The agency said it learned of the development from sources close to the archbishop but added that it had no further details. Gänswein was born in the village of Riedern am Wald in the Black Forest in Germany in 1956. He joined the Congregation for Divine Worship in 1995 before moving to the Congregation for the Doctrine of the Faith. In 2003, he became personal secretary to Cardinal Ratzinger. He was appointed prefect of the pontifical household in 2012, and continued in the role after the election of Pope Francis the following year.
