Pope Francis has signed off on the miracle needed to make Mother Teresa a saint.
The Pontiff has recognised a 'miracle' she performed on a Brazilian cured of brain tumours.
Although no date has been set for the canonization, Italian media speculates it will take place next September 5th, the 19th anniversary of her death.
Mother Teresa won the 1979 Nobel Peace Prize for her work caring for the poorest of the world's poor.
