A parliamentary commission in Georgia says the country's first post-Soviet president, Zviad Gamsakhurdia, may have been murdered in 1993.
Gamsakhurdia died from a gunshot to the head after being ousted from power and pursued by an enemy militia.
The authorities previously concluded that he had killed himself.
The commission wants a new official inquiry. But there are some doubts about its research, as it is run by Mr Gamsakhurdia's son and his associates.
The commission says witness statements from the time are contradictory and the wounds inflicted by the bullet suggest someone else was holding the gun.
Mr Gamsakhurdia was elected president after Georgia's independence in 1991, but was soon ousted after allegations of authoritarianism.
The commission is run by his son Konstantine Gamsakhurdia and is strongly backed by the government, the BBC's Damien McGuinness reports from the capital Tbilisi.
