South Korean President Lee Jae Myung has nominated Han Seong-sook, a seasoned technology executive and current cabinet minister, as the next Prime Minister of the Republic of Korea. Upon formal approval by the National Assembly, she will succeed the outgoing Prime Minister, Kim Min-seok, who is stepping down to pursue party leadership. This appointment marks a significant milestone as Han Seong-sook is set to become only the second woman to lead the South Korean cabinet in the nation’s history.
The Nomination of Han Seong-sook
President Lee Jae Myung announced the nomination as part of a strategic cabinet reshuffle following his first year in office. The Presidential Chief of Staff emphasized that the selection of Han Seong-sook is intended to accelerate South Korea’s transition into the artificial intelligence (AI) era while ensuring that technological advancements benefit small businesses and local economies. Han currently serves as the Minister of SMEs and Startups, a role she has held since July 2025.
The outgoing Prime Minister, Kim Min-seok, who served as the first premier of the Lee administration, is stepping down to contest the leadership of the ruling Democratic Party of Korea (DPK). The transition is expected to be smooth, as the DPK holds a majority in the 300-member National Assembly, the country’s unicameral legislature. However, the nominee must still undergo a rigorous personnel hearing to examine her ethical standards and professional competence before a final plenary vote.
Profile: A Tech Visionary in Governance
Han Seong-sook brings a unique blend of corporate leadership and administrative experience to the Prime Minister’s office. Born in 1967, she graduated from Sookmyung Women’s University with a degree in English Language and Literature. She began her career as a journalist for technology magazines before transitioning into the burgeoning internet sector in the late 1990s. Han was a founding member of Empas, an early competitor in the South Korean search engine market.
Her most prominent role was at Naver Corporation, South Korea’s largest internet portal and technology conglomerate. In 2017, she made history as the company’s first female CEO, leading it through a period of massive global expansion. During her five-year tenure, she oversaw the launch of Naver Pay, the international growth of Webtoon, and major acquisitions in the global content market. In July 2025, she joined the public sector as the Minister of SMEs and Startups, where she focused on digitizing traditional businesses and fostering the startup ecosystem.

Role of the Prime Minister in South Korea
In South Korea’s presidential system, the Prime Minister serves as the principal executive assistant to the President. While the President holds supreme authority as both the Head of State and the Head of Government, the Prime Minister manages the day-to-day operations of the executive branch and directs the various ministries under the President’s orders.
Under Article 86 of the Constitution of the Republic of Korea, the Prime Minister is appointed by the President. However, unlike other cabinet members, the Prime Minister’s appointment requires the formal consent of the National Assembly. The candidate must face a personnel hearing and secure a majority vote in a plenary session. The Prime Minister is the first in the line of succession; should the President be incapacitated, the Prime Minister assumes the role of Acting President.
Key Functions of the Prime Minister
The Prime Minister holds several vital responsibilities in the South Korean governance structure. As the second-highest political official, the Prime Minister provides counsel and administrative support to the President while overseeing the implementation of policies across all executive ministries and departments. Furthermore, the Prime Minister serves as the vice-chair of the State Council, which is the highest executive policy-making body in the country. Another crucial responsibility includes ensuring consistency and coordination among various government agencies to achieve the administration’s national objectives.
Historical Milestone for Women in Leadership
The nomination of Han Seong-sook is a landmark event in South Korean politics, which has traditionally been dominated by male leadership. If her appointment is confirmed, she will become the second female Prime Minister in the history of the Republic of Korea. The first woman to serve in this capacity was Han Myeong-sook, who held the office from April 2006 to March 2007 under the administration of President Roh Moo-hyun.
While Chang Sang was the first woman ever nominated for the premiership in 2002, her appointment was rejected by the National Assembly following her confirmation hearing. Therefore, Han Seong-sook’s potential inauguration reflects the slow but steady progress of gender representation in high-level governance. Her transition from being the first female CEO of a major tech giant like Naver to the second female Prime Minister underscores a shift towards valuing diverse professional expertise in national leadership.
The Political Context of the Cabinet Reshuffle
The nomination of a new Prime Minister is part of a broader cabinet reshuffle initiated by President Lee Jae Myung to mark the first anniversary of his inauguration. Following the local elections held in early June 2026, the administration is seeking to revitalize its reform agenda. The reshuffle is intended to align the cabinet’s working methods with the President’s six major reform tasks, which include regulatory, financial, and labor reforms.
By bringing in a technology veteran like Han Seong-sook, the government signals its commitment to maintaining South Korea’s competitive edge in the global digital economy. The transition also allows the ruling Democratic Party of Korea to regroup, as the outgoing Prime Minister Kim Min-seok prepares for a leadership role within the party. This strategic realignment is seen as an effort to bolster public support and ensure the effective execution of the administration’s long-term developmental goals.
