Tuhia he haere tonu mo tenei waahanga - I te tau 1950, i murua a Aybar ka tiimata te mahi ture i Istanbul. I haere tonu ia ki ana tuhinga whakahee, ka tiimata ki te whai waahi ki nga whakahee ki te kawanatanga, i arahi ki tana mauhere tuarua. Whai muri i tana tukunga mai i te whare herehere i te tau 1962, ko ia te kaiarahi tuatahi o te Rōpū Kaimahi o Turkey. I muri noa iho i tana eke ki te kaiarahi o te roopu ka tiimata te whakaaro o nga maatauranga ki te roopu. Ko te pono o Aybar i kukume i nga akonga ki te roopu Hei kaiarahi o te roopu, ko ia me ona hoa te kawenga mo te aronga me te angitu o te roopu. Ko tētahi o ngā kaupapa matua o te rōpū, ko te ātete ki te whakawhiwhi o Turkey ki te mana o Amerika. I whakahe a Aybar i te whakaekenga a te Soviet Union ki Czechoslovakia
nā tēnei i puta ai ngā tautohetohe i roto i te rōpū. I te tau 1971 i wehe ia i te TİP na te rereketanga o tana whakaaro ki te kaiarahi o te roopu mo te take o Czechoslovakia. I te tau 1975 i whakatuhia e ia te Pāti Socialist (i muri mai ka kiia ko Socialist Revolution Party). I katia tēnei rōpū e te whakatikatika hōia i te tau 1980. He mema ano a Aybar o te International War Crimes Tribunal i whakatuhia e Bertrand Russell. I whanau a Mehmet Ali Aybar i Istanbul ka mate ia i te 10 o Hurae 1995 i İstanbul.
