The president of Georgia (tr) is the ceremonial head of state of Georgia as well as the commander-in-chief of the Defense Forces. The constitution defines the presidential office as "the guarantor of the country's unity and national independence." The president is largely a figurehead as in many parliamentary democracies. Executive power is vested in the Government and the prime minister. The office was first introduced by the Supreme Council of the Republic of Georgia on 14 April 1991, five days after Georgia's declaration of independence from the Soviet Union. The president serves a five-year term. The current president is Salome Zourabichvili. Because of Georgia's transition to a fully parliamentary system she is the last president to be elected directly by the citizens. Any citizen of Georgia having the electoral right, who has attained the age of 40 and who has lived in Georgia for at least 15 years, may be elected President of Georgia. The office cannot be held by a citizen of Georgia who is simultaneously the citizen of a foreign country. The president of Georgia shall not be a member of a political party. According to the 2018 version of Georgia's constitution, starting in 2024, the president will be elected for a five-year term by the 300-member Electoral College, consisting of all members of the Parliament of Georgia and of the supreme representative bodies of the autonomous republics of Abkhazia and Adjara, also members from the representative bodies of local-self-governments (municipalities). The same person may be elected President of Georgia only twice. No less than 30 members of the Electoral College shall have the right to nominate a candidate for the president of Georgia. The election of the president of Georgia is appointed by the Parliament for October. One third of the total number of the members of Parliament has the right to raise the question of impeachment of the president of Georgia. They can be considered impeached if the decision is supported by at least two thirds of the members of Parliament.
