133 cardinals will return to the Sistine Chapel this morning to begin the second round of voting in the papal conclave.
Black smoke billowed from the building's chimney just after 8pm Irish time last night signifying the first round of voting had been unsuccessful.
The result was delayed by around 2 hours with the Vatican saying several cardinals needed help with translation issues.
Ruth Gledhill is the assistant editor of Catholic news magazine The Tablet.
She says delays should be expected during this process.
