As deputy from Isparta, Demirel became Turkey's 14th Prime Minister. In the next elections on 10 October 1969, his party was the sole winner by a landslide once again. Demirel presided over the laying the foundations of the Keban Dam, the Bosphorus Bridge and an oil pipeline between Batman and İskenderun. Despite his economic reforms which stabilised inflation, he resigned as Prime Minister after his budget was blocked by parliament, but formed his third government shortly after. He resigned after the military memorandum of 12 March 1971, which had been caused by a disagreement between the government and military over the Cyprus dispute, an escalation of tensions with Greece and growing political violence. He was also accused of deviating from the principles of Mustafa Kemal Atatürk, which he denied.
