Pope Francis has died at the age of 88, a day after appearing in the Vatican’s St Peter's Square to wish worshippers a happy Easter Sunday.  
 
Earlier this year, he was treated in hospital for five weeks with an infection, but had been discharged. 
The Argentinian pontiff, who ushered in a swathe of reforms over his 12-year papacy, symbolised to many an increasingly modern, progressive, and inclusive church.
