As a means to check the opposition, the military authority created the Korean Central Intelligence Agency (KCIA) in June 1961, with Kim Jong-pil, a relative of Park, as its first director. In December 1962, a referendum was held on returning to a presidential system of rule, which was allegedly passed with a 78% majority. Park and the other military leaders pledged not to run for office in the next elections. However, Park became presidential candidate of the new Democratic Republican Party (DRP), which consisted of mainly KCIA officials, ran for president and won the election of 1963 by a narrow margin.
