Pope Francis, who has been in hospital for 10 days now, is critical with mild signs of kidney failure. There is growing speculation about the 88-year-old pontiff’s successor. Who could it be?

The pope was admitted to Rome’s Gemelli hospital on February 14 after experiencing difficulty breathing for several days and subsequently had pneumonia diagnosed in both lungs.

The Vatican No. 2, Cardinal Pietro Parolin, is to lead the first prayer on Monday evening. Francis, who has double pneumonia and the early stages of kidney insufficiency, was awake and in good spirits Monday.

Pope Francis’ medical team says the pontiff's condition isn’t life-threatening. But they said Friday that Francis isn't out of danger.

With Pope Francis remaining in critical condition fighting a complex respiratory infection and bilateral pneumonia, the cardinals and curial officials in Rome have organized a rosary and special Mass for the pontiff.
