Cardinals enter seclusion ahead of secret conclave to elect new pope

Cardinals who will take part in the secret conclave to elect a new pope began checking into two Vatican hotels on Tuesday, where they will be barred from contact with the outside world as they decide who should succeed Pope Francis.

The conclave will start behind the closed doors of the Sistine Chapel on Wednesday afternoon, with all cardinals under the age of 80 able to vote on who should be the next leader of the 1.4-billion-member Church.

The race to succeed Francis, who died last month, is seen as wide open. Although a few names have been cited as possible front-runners, several of the 133 cardinals expected to vote in the conclave have said they do not know who will become the next pope.

"I have no guess," Cardinal Robert McElroy said during a visit to a parish in Rome on Monday evening. The conclave process is "profound and mysterious," said McElroy, the archbishop of Washington, D.C. "I can give you no insights into who is ahead," he said.

Some cardinals are looking for a new pope who will continue with Francis' push for a more transparent, welcoming Church, while others are seeking retrenchment to more traditional roots.

Conclaves are often spread out over several days, with multiple votes held before a contender wins the necessary three-quarters majority to become pope.

During the conclave period, the voting cardinals will stay in two Vatican guesthouses and take an oath to remain out of contact with anyone not participating in the secret vote.

Francis had a priority of appointing cardinals from countries that had never had them before, such as Haiti, South Sudan and Myanmar.

This conclave will be the most geographically diverse in the Church's 2,000-year history, with clerics from 70 countries taking part.
