VATICAN CITY, March 13: In a surprise choice, Jorge Mario Bergoglio of Argentina was elected to be the new leader of the troubled Roman Catholic Church on Wednesday, and said he would take the name Francis I.

Pope Francis, 76, appeared on the central balcony of St Peter’s Basilica just over an hour after white smoke poured from a chimney on the roof of the Sistine Chapel to signal he had been chosen to lead the world’s 1.2 billion Roman Catholics.

The choice of Bergoglio was announced by French cardinal Jean-Louis Tauran with the Latin words “Annuntio vobis gaudium magnum. Habemus Papam” (“I announce to you a great joy. We have a pope.”) Francis becomes the 266th pontiff in the church’s 2,000-year history at a time of great crisis and difficulty.

Although a conservative, he is seen as a reformer and was not among the small group of frontrunners identified before the election.

He also went against one of the main assumptions before the election, that the new pope would be relatively young.

He is the oldest of most of the possible candidates and was barely mentioned in feverish speculation about the top contenders before the conclave.

FIRST JESUIT POPE: He is the first Jesuit to become pope.

The decision by 115 cardinal electors sequestered in a secret conclave in the Sistine Chapel came sooner than many experts expected because there were several frontrunners before the vote to replace Pope Benedict, who resigned last month.

The cardinals faced a thorny task in finding a leader capable of overcoming crises caused by priestly child abuse and a leak of secret papal documents that uncovered corruption and rivalry inside the church government, or Curia.

The wave of problems is thought to have contributed to Pope Benedict’s decision to become the first pontiff in 600 years to abdicate.

Thousands of people sheltering from heavy rain under a sea of umbrellas had occupied the square all day to await the decision and the crowd swelled as soon as the white smoke emerged.

They cheered wildly and raced towards the basilica as the smoke billowed from a narrow makeshift chimney and St Peter’s bells rang.
