About Spyros Markezinis
Spyridon "Spyros" Markezinis was a Greek politician, longtime member of the Hellenic Parliament, and briefly the Prime Minister of Greece during the aborted attempt at metapolitefsi (democratization) of the Greek military regime in 1973. Markezinis’s Party eventually won a seat in parliament in the 1958 elections. The New Party won 2.5% of the vote in the 1950 parliamentary elections, enough for a single seat (held by Andreas Stratos) in the new parliament.
