Felipe wrote: "Upon receiving, with profound sadness, the news of the death of His Holiness Pope Francis, I wish to convey to you, on behalf of myself, the Government, and the people of Spain, our deepest condolences.

"We will always continue to be inspired by his conviction in the need to bring encouragement and comfort to the poorest and most needy, and by the importance he placed on dialogue and consensus in achieving a more just and united world.
"In light of our grief over his loss, the Queen and the entire Royal Family join me in conveying to the entire Catholic Church our condolences and affection, as well as our prayers for his eternal rest.
