He was a People's Deputy of Ukraine from 1994 to 2012, representing Poltava Oblast until 2002 and later being elected from the proportional list of the Yulia Tymoshenko Bloc.

Hryhoriy Omelianovych Omelchenko was born 4 May 1951[1] in Novoselytsia, in Ukraine's central Poltava Oblast under the Soviet Union.

[4] He was subsequently re-elected from Ukraine's 146th electoral district in 1998 as an independent,[5] though he was deputy chairman of the Ukrainian Republican Party from December 1999 to November 2005.

[6] He was re-elected in the 2002 Ukrainian parliamentary election, this time as the third candidate on the proportional list of the Yulia Tymoshenko Bloc.

Serhiy Mishchenko, a fellow member of the alliance, claimed that Omelchenko had been removed due to having left the Batkivshchyna party, but BBC News Ukrainian alleged that it had come after he issued a parliamentary request to President Yushchenko on details regarding the Artek affair, an incident in which three deputies from the Yulia Tymoshenko Bloc were accused of child rape.
