The leader of Italy's biggest political party has called for the president to be impeached after he vetoed a choice for finance minister.
Luigi Di Maio of the populist Five Star Party said President Sergio Mattarella had caused an "institutional crisis".
Italy has been without a government since elections in March because no political group can form a majority.
Luigi Di Maio said Italy now faced an institutional crisis But BBC reports that in Rome that such an arrangement is unlikely to last and early elections may have to be called.
There is now a real argument between the president and the populists about Italy's position in the EU.
