Italian Prime Minister Matteo Renzi said he would resign following a defeat on Sunday in a referendum over his proposals for constitutional reform, opening the way for new elections which could see an anti euro party win power.
Almost 60% of the voters voted against his proposals. The 20% margin of the No camp will make it difficult for the Italian president to ask Renzi to form a new government and delay elections.
Renzi said he would convene his cabinet and then hand in his resignation to President Sergio Mattarella.
The clear No vote in the Italian referendum makes the result for Establishment candidate Alexander van der Bellen as president in Austria even more extraordinary, and is bound to raise questions given the two previous elections with proven cases of irregularities.
