Who will be the next pope? The decision could have a profound impact on the Catholic Church and the world's 1.4 billion baptised Roman Catholics.

It also promises to be a highly unpredictable and open process for a host of reasons.

The College of Cardinals will meet in conclave in the Sistine Chapel to debate and then vote for their preferred candidates until a single name prevails.

With 80% of the cardinals appointed by Pope Francis himself, they are not only electing a pope for the first time, but will offer a broad global perspective.

For the first time in history, fewer than half of those given a vote will be European.

And although the college may be dominated by his appointments, they were not exclusively "progressive" or "traditionalist".

For those reasons, it is harder than ever to predict who will be elected the next pope.

Could the cardinals elect an African or an Asian pope, or might they favour one of the old hands of the Vatican administration?

Here are some of the names being mentioned as Francis's potential successor.
