An opinion poll suggests Pope Francis is more popular than any world political leader.
The poll by WIN/Gallup International indicated Catholics and Jews had the most favourable opinion of the Pope.
More than half of the world's protestants, and even the majority of atheists and agnostics, view him favourably.
About 1000 people were questioned in 64 countries.
WIN/Gallup gave the Pope a net score, the difference between favourable and unfavourable opinions, of +41, ahead of the United States President, Barack Obama, on +30 and British Prime Minister, David Cameron, on +10.
