London-born boy who died aged 15 to become first millennial saint

Second posthumous miracle attributed to leukaemia victim Carlo Acutis, qualifying him for canonisation

A London-born teenager who died of leukaemia aged 15 is to become the Catholic church's first millennial saint.

Carlo Acutis was a computer prodigy who helped to spread Roman Catholic teaching online before his death in 2006. On Thursday, Pope Francis decreed that a second posthumous miracle has been attributed to Acutis, qualifying the teenager for canonisation.
