Following the passing of Pope Francis on Easter Monday, Catholics across the globe will turn their attention to his successor.

Prior to his death aged 88, Pope Francis led the church for 12 years, bringing reforms and, often controversial, changes to the Vatican.
The Argentinian was born Jorge Mario Bergoglio in Buenos Aires on the 17th of December 1936.
Seen as an outsider when he was chosen to succeed Benedict the 16th in 2013, the Argentinian was the first Latin American and the first Jesuit to lead the Roman Catholic Church.
The Pontiff appeared to the public for the final time on Sunday, as he delivered an Easter blessing to hundreds of worshippers.
What happens next?
The Vatican has confirmed the Pope’s body will be lying in state in the coming days.
Thousands, if not millions, of people are expected to flock to Vatican City to see the Pope.

A funeral is expected to take place in the next four days and then the process of picking the next Pope will begin.
The Catholic College of Cardinals convening to elect a new pope is one of the oldest methods of electing a head of state that remains in use to the present day.
While the voting for the pope is billed as secret, with each cardinal guided only by his faith in God, Berger's film explored how the process can be an exercise in consensus-building that cements fidelity to the Church's new leader among the inner circle.
The papal election resembles how decisions were made in Europe some 700 years ago, before elected monarchies were replaced by hereditary monarchies, according to Bruce Bueno de Mesquita, professor of politics at New York University.
Cardinals are bishops and Vatican officials from all over the world, personally chosen by the pope and recognisable by their distinctive red vestments.
Only cardinals under the age of 80 are eligible to vote in a conclave - they are known as the cardinal electors, and their number is limited to 120.
Women are barred from the priesthood, and therefore from becoming pope, in the Catholic Church - with the ban based on the belief that Jesus chose only men to be his apostles.
Who are the top candidates?
CARDINAL FRIDOLIN AMBONGO BESUNGU
Congolese cardinal Besungu, 65, was at odds with most of Pope Francis’ liberal reforms, hitting out at his decision to accept gay people in the Church.
He is the youngest of the frontrunners and would likely undo many of the changes Francis worked hard to implement.
CARDINAL PIETRO PAROLIN
The Vatican's Secretary of State is the leading candidate to take on the role of Pope.
He was an ally of Francis, albeit less liberal in his views, and would be seen as an extension of Francis’ legacy.
CARDINAL WIM EIJK
Former doctor Eijk is perhaps the most conservative candidate in the running.
He once described remarrying as a “form of structured and institutionalised adultery."
He has also described Francis’ embrace of protestants as "completely incomprehensible".
CARDINAL RAYMOND BURKE
Another hardline conservative, Burke, hailing from the USA, is a staunch traditionalist.
He has been critical of Pope Francis’ attempts to welcome LGBTQ+ people into the church.
CARDINAL PETRO ERDO
Erdo is the former President of the Council of Bishops Conferences of Europe and is another conservative voice in the Church.
From Hungary, he is a Marian, which means he worships Mary, the mother of Jesus.
He once compared helping refugees to human trafficking.
CARDINAL MATTEO ZUPPI
One of the more liberal candidates, Zuppi was a favourite of Pope Francis.
He threw his support behind Ukraine in the months after Putin’s invasion - meeting with President Zelenskyy.
He also wrote in his 2018 book that the Church should seek dialogue with "our LGBT brothers and sisters".
CARDINAL MARIO GRECH
A moderate voice in the Church - Grech has not supported Francis' progressive agenda but has spoken of the need for dialogue.
He was elevated to cardinal by Pope Francis in 2020.
The Conclave
Four rounds of balloting are taken every day until a candidate receives two-thirds of the vote.
Berger's film, based on the 2016 novel by Robert Harris, portrays how the cardinals vote by secret ballot, processing one by one up to Michelangelo's fresco of the Last Judgment, saying a prayer and dropping the twice-folded ballot in a large chalice.
The result of each ballot is counted aloud and recorded by three cardinals.
If no-one receives the necessary two-thirds of the vote, the ballots are burned in a stove near the chapel with a mixture of chemicals to produce black smoke.
The process can go to multiple rounds with the same people theoretically getting the same number of votes each time as cardinals wait to see who loses support first.
But slowly, cardinals who voted for someone who only received a very small number of votes are likely to add their vote to one of the stronger candidates in the next round.
Factions may be able to make their views known during informal chats between votes, with key parts of Berger's film showing heated discussions among cardinals in the canteens and cinemas of the Vatican.
When a cardinal receives the necessary two-thirds vote, the dean of the College of Cardinals asks him if he accepts his election.
If he accepts, he chooses a papal name and is dressed in papal vestments before processing out to the balcony of St Peter's Basilica. The ballots of the final round are burned with chemicals producing white smoke to signal to the world the election of a new pope.
The senior cardinal deacon announces from the balcony of St Peter's "Habemus Papam" ("We have a pope") before the new pope proceeds out and imparts his blessing on the city of Rome and the world.
