Cardinal George Pell will receive a send-off by Pope Francis at a service at the Vatican amid fresh revelations the pair clashed over the direction of the Catholic church.
Formerly Australia's most senior Catholic figure, Cardinal Pell died in Rome this week at the age of 81 from heart complications following hip surgery.
Following his death, it was revealed the conservative cardinal criticised Pope Francis in anonymous memos, calling his papacy a "disaster" and "catastrophe".
