The ballot battle for a new pope enters day two with accompanying black smoke signifying a catholic deadlock.
Though conclaves have lasted months and even years in recent history, they have never taken more than a week.
The media and bookmakers currently favour the previous number two in the Catholic Church, Secretary of State Pietro Parolin.
A new pope will poll a two-thirds majority to emerge during the election process that will commence on Wednesday.
The cardinals are to decide on the exact time of the burial of the late head of the Catholic Church, which usually takes place four to six days after death.
