Ankara Chief Public Prosecutor's Office announced on Thursday that the absolute reason which caused the death of former Turkish President Turgut Ozal could not be determined following the examination on Ozal's exhumed body according to the Turkish Forensic Institute report.

Ankara Chief Public Prosecutor's Office will continue the investigation on the demise of former President Ozal.

A separate forensic institute autopsy on the exhumed body of Ozal, who led Turkey out of military rule in the 1980s, was completed on Tuesday.

"In my view, the forensic institute report has not eliminated the suspicions," Deputy Prime Minister Bekir Bozdag told reporters in parliament on Wednesday, saying the investigation was continuing.

"If there is poison in the body where did it come from?"

There have long been rumours that Ozal, who died of heart failure in 1993 aged 65, was murdered by an alleged organisation within the Turkish establishment in which military and security officials supposedly colluded with criminal elements.

The "deep state" is believed by many in Turkey to have been a clandestine network set up by nationalist groups operating in the shadows and murdering anyone deemed to pose a threat.

His moves to end a PKK conflict and create a Turkic union with central Asian states have been cited as motives for would-be enemies and he survived an assassination bid in 1998.
