ANKARA, TURKEY — More than a quarter of a million people rallied Saturday in the Turkish capital to voice secularists' opposition to a run for the presidency by the country's prime minister, who is affiliated with an Islamist party.
Prime Minister Recep Tayyip Erdogan is expected to announce soon, perhaps this week, whether he will be his party's presidential nominee.
Lawmakers are to elect a president next month, and because Erdogan's party has a substantial parliamentary majority, announcing his candidacy would be tantamount to claiming the post.
The rally Saturday was organized by Turkey's secular establishment, and followers were bused in from around the country. By the standards of political protests here it was large, but probably not large enough to deter Erdogan if he has decided to seek the presidency.
Still, the protest was a determined show of symbolic force by the secularist camp.
"Turkey is secular and will stay that way!" marchers chanted. Many held banners bearing pictures of the republic's revered founding father, Kemal Ataturk, who decreed a strict separation of religion and state. The marchers' route took them near Ataturk's mausoleum.
Ece and Muge Kaplan, sisters in their 20s, carried a huge Turkish flag as they marched.
"We don't want to lose secularism. He's going to destroy the secular regime," Muge Kaplan said of Erdogan. "We don't want to become Iran."
Her sister chimed in: "We believe in Islam; we are Muslims. But we don't want it to become our whole way of life."
Although Erdogan's Justice and Development Party has Islamist roots, the prime minister has allied with secularists on some crucial domestic issues, such as the bid for membership in the European Union.
But he also has stoked secular anxieties with moves such as urging that the ban be lifted on wearing Islamic-style head scarves in schools and government offices.
He has been a popular prime minister, credited with helping generate strong economic growth during his four-year tenure. However, the notion of him as head of state makes secularists queasy, particularly because Erdogan's party has spoken openly of taking steps to strengthen the power of the executive branch.
Turkey's powerful military, which considers itself the guardian of the secular system, has already weighed in. In a clear swipe at Erdogan, the army chief of staff, Gen. Yasar Buyukanit, said Thursday that the military hoped someone "loyal to the principles of the republic" would be elected.
