Keko worked as a journalist for the literary newspaper "Drita". When the Stalinist system dissolved in early '90s, Keko joined the opposition movement and the main opposition party, the Democratic Party of Albania, and was elected to Albanian parliament in March 1992. He quickly became critical of the newly elected Albanian President, Sali Berisha, whom he accused of authoritarianism. He and six others were expelled from the Democratic Party in August 1993 and, with two others who voluntarily left the party, formed the Democratic Alliance Party.
