Vassilis Leventis is the fourth child of Apostolos and Gregoria Leventis. The Leventis family moved to Piraeus where Vassilis Leventis graduated from high school and in 1969 he was admitted to the Civil Engineering department of the National Technical University of Athens. During the '70s he ventured into discography.
In a 1992 congress he decided to found the Union of Centrists, which strove to become "the political continuance of the centrist expression in Greece". Leventis aimed to become part of the legacy of some great politicians of the past, such as Eleftherios Venizelos and George Papandreou, senior. However, his total influence has been marginal, with 1.2% of the total vote (in the 1994 European Parliament election) being his highest achievement ever. His percentage has furthermore declined to 0.38% at the European parliament elections of 2009  and to 0.27% in the Greek legislative election, 2009.
Vasilis Leventis expresses his political opinion through his Antidiaplokí (Αντιδιαπλοκή) weekly newspaper and his TV show that has been hosted in several stations so far.
His views are placed in the centre of the political spectrum with particular emphasis on policies that are "rational", transparent, squarely opposed to corruption, in favour of the weaker social classes (workers, pensioners, farmers, single parents, etc.), hostile to the concentration of power in just a few individuals and reform of the Greek political life.
Leventis himself is unreservedly and nearly polemically critical of mainstream Greek political parties and their leaders. He asserts that Greek politicians are in league with big business interests who control the mainstream media and as a result of this criticism he has been deliberately excluded from publicity, which in his opinion, is the factor that has caused his party to exist only in the margins of Greek politics. His frequent use of expletives and his animated style of speaking have led him often to be the object of jokes at his expense, but have also elevated some snippets of his TV shows to cult status.
