Joining the Mikheil Saakashvili-affiliated United National Movement in 2008, he would be reelected that year and again in 2012, before leaving the party weeks after its defeat to Georgian Dream (GD).
In 2020, he left GD and created the Progress and Freedom party with fellow businessman Tsezar Chocheli, and merged it within the UNM-led Strength is in Unity electoral bloc, winning a seat in that year's parliamentary election after a campaign that was characterized for a high level of violent incidents.
[4] In 1995, Kakha Okriashvili and Gocha Gogilashvili, a doctor from Dedoplistsqaro, founded the PSP pharmacy network company, of which he became director until joining the public sector in 2003.
[12] During the 2003 parliamentary election, Kakha Okriashvili ran as an independent candidate for the Dmanisi Majoritarian District after incumbent Teimuraz Tsikhelashvili refused to run for reelection.
Though the election results would be cancelled after the revelation of massive voter fraud that led to the Rose Revolution, his district's votes were not annulled by the Constitutional Court, thus allowing him to be inaugurated on 22 April 2004.
Running against three candidates, including Tahir Shaverdov who was nominated by a nine-party opposition bloc,[13] Parliamentary Speaker Nino Burjanadze campaigned for him[14] and he won with 93% of the vote, one of the largest victories in the country.
[15] In the 2012 legislative polls, Kakha Okriashvili was once again nominated by UNM to run for reelection and he ran against five candidates, including the Georgian Dream nominee Paata Khizanishvili, a close friend of Russia-affiliated businessman Bidzina Ivanishvili.
[22] Okriashvili and the rest of NIM formally joined the Georgian Dream faction in Parliament after the withdrawal of the Free Democrats from the ruling coalition in November 2014, thus safeguarding GD's parliamentary majority.
[29] During the 2018 presidential race, he endorsed and contributed to the campaign of GD-backed Salome Zourabichvili,[30] while UNM MP Nika Melia accused him of managing a "voter fraud scheme" in Dmanisi.
In 2013, a report by Transparency International alleged that MPs Okriashvili, Davit Bezhuashvili, and Gocha Enukidze were using a "revolving door", choosing to affiliate themselves with whichever party was in power.
Moreover, Okriashvili favored a deal to end the political crisis including the release from prison of Giorgi Rurua, Irakli Okruashvili, and Gigi Ugulava, instead of an electoral reform.
[50] On 20 July 2020, GD nominated sitting MP Gogi Meshveliani to run in the newly-created 14th Parliamentary District, made up of Dmanisi, Tsalka, Bolnisi and Tetritsqaro, thus pushing Okriashvili out of the party.
[53] On 4 September, Okriashvili signed a deal merging P&F within the Strength Is in Unity electoral bloc led by the United National Movement, while he personally became one of UNM's largest donors.
[70] During one of his campaign events in the village of Nakhiduri, journalist Jeykhun Muhammadli of opposition-leaning channel Mtavari TV was prevented by law enforcement officers from covering it.
Following allegations of massive voter fraud, P&F was one of a dozen opposition parties to refuse to recognize the results, calling for repeat elections, and Okriashvili formally boycoted his seat.
[77] On 23 June 2021, he backed the proposal by MP Mamuka Khazaradze to resume the boycott after Parliament confirmed the nomination of several Supreme Court justices, despite a moratorium on judicial appointments being a key part of the EU-facilitated agreement.
He has remained an activist in Dmanisi: in May 2021, he accused the government of empowering local criminal groups after several injuries took place during a brawl between ethnic Azerbaijani and Georgian families.
