King Charles and Queen Camilla have had a private meeting with Pope Francis at the Vatican where he wished them a happy 20th wedding anniversary. In a statement released by Buckingham Palace, the King and Queen said they were "delighted the Pope was well enough to host them - and to have had the opportunity to share their best wishes in person".

From Palm Sunday to Easter Sunday, there are six major liturgies, all of which normally involve the pope. This year, can Pope Francis take part without jeopardizing his recovery?
