must first be established by a resolution of parliament, adopted, on the proposal of not less than fifty members of parliament, by a three-fifths majority of the total number of its members, in two ballots, held at least one month apart. The resolution must define specifically the provisions to be revised. Upon a resolution by parliament on the revision of the constitution, the next parliament must, in the course of its opening session, decide on the provisions (among those specifically defined in the original resolution) that will be revised by an absolute majority of the total number of its members (50% plus one majority). In the event that a proposal for revision of the constitution (in the previous parliament) receives the majority of the votes of the total number of members but not the three fifths majority specified, the next parliament may, in its opening session, decide on the provisions to be revised by a three-fifths majority of the total number of its members. A parliament endowed by its predecessor with the power to revise the constitution is called a "revisional parliament" (). Following the collapse of the military junta in 1974, the parliament that was elected was called the "5th revisional" as it operated under, and amended, the 1952 constitution. The resulting constitution of 1975 was essentially an entirely new constitution, especially since it incorporated the outcome of the 1974 plebiscite that established a parliamentary republic in place of a constitutional monarchy. Nevertheless, because it was officially deemed a revision of the 1952 constitution it was not called a "constituent parliament". Since the adoption of the new constitution in 1975, this has been revised on three occasions: in 1986, in 2001 and in 2008. A minimum of five years must elapse after the successful conclusion of the revision process, before another may be initiated. Electing the president The president of Greece is elected by the parliament on an open voting by roll-call for a term of five years. In conformity with the constitution, the president is elected on a two-thirds majority (200 votes) out of the total number of MPs and in case of no majority, the ballot is repeated after five days. Should the second ballot fail, the process is repeated after five days and president is elected the person receiving a majority of 3/5 (180 votes). Should the third ballot fail to produce the said qualified majority
