ANKARA: Turkish President Tayyip Erdogan laid out his case for a new constitution and a more powerful presidency on Thursday, saying it was not a matter of personal ambition but a necessity in a country whose parliamentary system he said was out of date.

Erdogan, who won Turkey’s first direct presidential election in August 2014, said a head of state elected by the people should have more than a symbolic role. Previously, Parliament had picked Turkey’s president.

The current situation, in which both the prime minister and president are popularly elected, is unsustainable, Erdogan said in a speech to more than 1,000 members of civil society groups that was seen as the start of a public campaign for the changes.

“In building the ‘New Turkey’, we think Turkey needs an executive presidential system and a new constitution. This discussion should not be presented as a matter of my personal ambition,” he told a packed conference hall. “If the presidential system is the right choice for Turkey’s future then it should be put into practice,” he said.

Erdogan served as prime minister for more than a decade and ran for the presidency in 2014 in the expectation of swift constitutional reform that would grant the head of state new executive powers. But his plans have been impeded in part because of opposition fears of creeping authoritarianism.
