The June 1989 Greek legislative election left the PASOK party of Andreas Papandreou in the minority, following a series of government scandals. New Democracy, however, now led by Constantine Mitsotakis, could not form a government despite its significant lead in the popular vote, because of changes to Greek electoral law that PASOK had voted into effect before the elections. The result was the formation of the first coalition government since the fall of the Greek dictatorship in 1974 and the first government to include the Communist left since 1944. The government was based on an alliance between ND and the Coalition of Forces of the Left and Progress, which then included the Communist Party of Greece, with a mandate to conduct a clean-up after the scandals. The agreement was for a short-term government which would last only until the process of parliamentary investigation of those Members of Parliament accused of involvement in the scandals had been completed. Tzannetakis was a compromise candidate for Prime Minister, given that the left refused to accept Mitsotakis in this role. In contrast, Tzannetakis was acceptable to the left because of his credentials from the anti-Junta resistance. In addition to the premiership, Tzannetakis also retained the portfolios of Foreign Affairs and of Tourism. The formation of a government bringing together the Greek right and the communist left was regarded as symbolising national reconciliation after the 1940s civil war. One of the government's acts was to burn all the secret police files held on Greek citizens during the post-Civil War period. The parliamentary investigation into the scandals concluded with the lifting of the parliamentary immunity of several former government ministers, including former Prime Minister Andreas Papandreou himself, and their referral to the justice system. This was the first time that a former Greek Prime Minister had ever been referred for trial. The Tzannetakis government also abolished the state monopoly on TV broadcasting and allowed private TV stations to function for the first time.
Aftermath
In accordance with the initial agreement among the coalition partners, the government resigned in October. Yiannis Grivas then formed a caretaker government until fresh elections could be held. New Democracy won these elections too, but once more could not form a government, despite tallying 46% of the vote, with PASOK coming second with 40%. In November an "ecumenical government", headed by Xenophon Zolotas, with the participation of all three political parties was formed, again with an agreement for a short-term mandate to last until the election of the President of the Republic, due the following March. In the Zolotas government, Tzannis Tzannetakis served as Minister for Tourism and National Defence. In the election of April 1990, for the third consecutive time within a year, New Democracy won, this time with an even more significant lead of 8% over PASOK, securing the party a one-seat majority. In the Mitsotakis government, Tzannetakis became Deputy Prime Minister, a post he held until the government fell in 1993. He remained a Member of the Greek Parliament until September 2007, when he announced his intention to retire from political activity. Tzannetakis died in an Athens hospital on 1 April 2010.
