From 1970 to 1974, Lencho, along with some Oromo nationalist, was working clandestinely to form OLF. In 1974, the
Marxist Derg staged a
coup d'état against Emperor
Haile Selassie. Late in 1974, Lencho, along with some other Oromo nationalist, went underground and officially launched the OLF for guerrilla army struggle against the Marxist Derg regime of
Mengistu Haile Mariam. Starting from the late 1970s until 1995, Lencho served as Deputy General Secretary of the OLF. He was the leading representative OLF's negotiation team with TPLF leader
Meles Zenawi and EPLF leader
Isaias Afwerki during the 1980s and early 1990s. He was also leading negotiator for the OLF during Ethiopian Transitional Government from 1991 to 1995. Late 1992, the transitional agreement between OLF and
TPLF fell apart, and the OLF quit the transition government to wage army struggle against
EPRDF. In late 1993, Lencho was expelled from OLF due to leadership fallout and an ideological difference with OLF leadership, particularly with the question Oromo
self-determination. Since the 1970s, the OLF push for establishing an independent state of Oromia. However, since the introduction of ethnic federalism in Ethiopia in 1995, several Oromo activists including the
Oromo People's Congress leader
Merera Gudina has been arguing for democratizing the Ethiopian State. Starting from late 1990s, Lencho became an advocate of preserving Oromo people's right by Democratizing Ethiopian state. He wrote two books – "Ethiopian State at the Crossroads" (Red Sea Press, 1999) and "The Horn of Africa as Common Homeland" (Wilfrid University Press, 2004) – in which he argues in favor of Democratizing Ethiopia. Later in 2013, Lencho with several former OLF activities launches Oromo Democratic Front (ODF) an opposition organization which is advocating for Oromo right in exile. On March 19, 2015, Lencho returned to Ethiopia after more than two decades of exile to fight for Oromo rights within the existing political structure in Ethiopia. However, the government of Ethiopia expelled Lencho and other ODF delegation team from Ethiopia within 24 hours. He currently resides in
Oslo,
Norway. He is associated with the Norwegian Research Institution, Fafo Institute for Applied International Studies (Fafo AIS). He works as a freelance analyst of political developments in the Horn of Africa. ==References==
