ISTANBUL: Turkey’s former president and Prime Minister Suleyman Demirel, a giant figure in the country’s politics for over half a century, died Wednesday, the state Anatolia news agency said. He was 90. In a remarkable career, Demirel survived his dismissal in two military coups and a ban on holding office to become president and one of Turkey’s most respected elder statesmen. Demirel served as prime minister on repeated occasions in the 1960s and 1970s and then again in the 1990s before serving as head of state from 1993-2000. He died of heart failure resulting from a severe respiratory tract infection, Anatolia said, quoting the private Ankara hospital where he was treated.
