Oh Chang-hee, the President of the South Korean Bobsleigh and Skeleton Federation (KBSF), has resigned from his post with just five months to go until the Pyeongchang 2018 Winter Olympic Games.
According to Yonhap News, the 54-year-old announced his intention to leave during a board meeting earlier this week.
It is claimed Oh feels responsible for "various controversies" within the organisation.
These include a supposed lack of transparency in the national team selection process and unfair treatment between members of the core team and reserve squad.
Oh, who had previously worked within the tourism industry, began his tenure as KBSF President in July 2016.
Prior to that, he had served as vice-president for a year.
Following Oh's departure, one of the two KBSF vice-presidents will take over as caretaker until a new President is elected.
It is reported that KBSF rules state the position must be filled within two months.
Bobsleigh is expected to be among South Korea's best hopes for an Olympic gold medal at Pyeongchang 2018.
In February 2016, Won Yunjong and Seo Youngwoo became the first Asian sliders to win an International Bobsleigh and Skeleton Federation World Cup overall title with victory in the two-man season finale in Königssee.
South Korea's two-man and four-man teams, as well as the two-woman squad, all failed to break into the top 15 of their events at Sochi 2014.
