A weary looking Pope Benedict celebrated his last public mass as Pontiff today, inside St Peter's Basilica where thousands gathered to celebrate Ash Wednesday.
Ash Wednesday is one of the holiest days of the Catholic faith, and marks the beginning of Lent, forty days before the celebration of Easter Sunday, by which time the church will have a new leader.
So, we're all shocked at the resignation of the Pope, but what happens next?
Pope Benedict XVI has made the announcement that he will resign as the head of the Roman Catholic Church due to his "advanced age."
Who will follow in Pope Benedict's footsteps? Is it time for an African pope?
