Kim Jong-il
Kim Jong-il (officially transcribed Kim Jong Il; ; ; 16 February 1941 – 17 December 2011) was the second Supreme Leader of North Korea.

O Kuk-ryol
O Kuk-ryol allegedly took part at a meeting of top leaders held immediately after Kim Jong-il's death on 17 December 2011 in order to plan funeral and succession. He was a member of the Kim Jong-il funeral committee. As a Kim loyalist, speculations named him as an possible successor of Kim Jong-un, and the regime appeared to be purging O's protégés in January 2011 to prevent him from being a threat to Jong-un. After the execution of Jang Sung-taek in December 2013, a powerful rival, O re-emerged as more of a public figure.
