Italy's former Prime Minister Matteo Renzi said he does not expect a new president to be elected on Thursday but thought that the centre-left and centre-right blocs would reach an agreement over a name on Friday.
"I don't think we'll wrap it up today. I think we will do it tomorrow," Renzi, the head of the centrist Italia Viva party, told Radio Leopolda.
Lawmakers failed to elect a new head of state for a third day running on Wednesday, with no consensus candidate emerging to replace outgoing President Sergio Mattarella.
A fourth round of voting will begin at 1000 GMT on Thursday, with an absolute majority now required to elect a successful candidate.
