Turkish Prime Minister Recep Tayyip Erdogan will address the country on Monday amid a deepening crisis prompted by a clash between secularists and Islamists over the country's political future, CNN reported. The move comes after Erdogan's foreign minister, Abdullah Gul, insisted he would not withdraw his candidacy for the Turkish presidency despite opposition from lawmakers, military chiefs, business leaders and a massive anti-government demonstration in Istanbul on Sunday. Gul's nomination has raised concerns among Turkey's secular establishment over growing Islamist influence within Erdogan's government.
