As cardinals prepare for the papal conclave to choose a new pope, Sky News explores potential candidates. Pietro Parolin, the Vatican's secretary of state, is considered a frontrunner if the next pontiff is Italian. Matteo Zuppi, the president of the Episcopal Conference of Italy and Archbishop of Bologna, is another likely candidate. Jose Tolentino de Mendonca, the prefect of the Dicastery for Culture and Education, and Peter Erdo, the Hungarian cardinal, are also possible contenders. Cristobal Lopez Romero, the Spanish Archbishop of Rabat, and Pierbattista Pizzaballa, the Latin Patriarch of Jerusalem, are additional potential candidates.
