* Prosecutors investigating suspicions Ozal was poisoned
* President Ozal helped shape modern Turkey
* Died of heart failure in 1993
An autopsy on the exhumed body late President Turgut Ozal, who led Turkey out of military rule in the 1980s, has revealed evidence of poisoning, a newspaper reported on Monday.
There had long been rumours Ozal, who died of heart failure in 1993 aged 65, was murdered by militants of the "deep state" - a shadowy nationalist strain within the Turkish establishment of the day. He had angered some with his efforts to end the Kurdish conflict and survived on assassination bid in 1988.
His body, dug up last month on the orders of prosecutors investigating suspicions of foul play in his death, contained the banned insecticide DDT and the related compound DDE at ten times the normal level, Today's Zaman cited sources from the state Forensic Medicine Institute (ATK) as saying.
"Ozal was most likely poisoned with four separate substances," the paper reported the sources as saying, also naming the toxic metal cadmium and the radioactive elements americium and polonium as substances found in Ozal's remains.
Forensic institute officials declined to comment.
Ozal, whose economic reforms easing the grip of the state on business helped shape modern Turkey, was in poor health. After undergoing a triple heart bypass operation in the United States in 1987, he kept up a gruelling schedule and remained overweight until he died.
His moves to end a Kurdish insurgency and create a Turkic union with central Asian states have been cited as motives for would-be enemies in "deep state", in which security establishment figures and criminal elements colluded.
It was Turkey's military leaders who appointed him as a minister after a period of military rule following a 1980 coup.
He went on to dominate Turkish politics as prime minister from 1983 to 1989. Parliament then elected him president, but those close to him believe his reform efforts displeased some in the security establishment.
While prime minister, Ozal survived an assassination attempt by a right-wing gunman in 1988 when he was shot at a party congress, injuring a finger.
Turkish political history has been littered with military coups, alleged anti-government plots and extra-judicial killings. A court is currently trying hundreds of people suspected of links to a nationalist underground network known as "Ergenekon" accused of plotting to overthrow the government.
A media report at the start of November said Ozal's autopsy had revealed high levels of the pesticide strychnine, but the ATK subsequently denied the report.
The head of the ATK has said the institute aims to complete its work in December and that its report would be handed over to prosecutors.
