Pope Francis has fuelled speculation that he could resign after postponing a trip to Africa and announcing an unusual meeting of cardinals.
Hobbled by pain in his knee and forced to use a wheelchair in recent weeks, the 85-year-old pontiff postponed a July trip to the Democratic Republic of Congo and South Sudan last week.
He also announced an unusual decision to hold a consistory to name new cardinals during a Vatican vacation month and arranged meetings to ensure his reforms stay intact.
