Ahn Cheol-soo

As head of the People's Party, Ahn was a strong advocate for merging with the center-right Bareun Party. The two leaders of the respective parties, Ahn and former presidential contender Yoo Seung-min, pushed forward with the merger which was completed in February 2018.

Although Yoo retained a leadership position within the new party and Ahn stepped down from any leadership role, as of March 2018 took on the role of leading the party's talent recruiting committee - a formal position speculated to signal his preparation to run for the Seoul mayorship later in the year.

Ahn was widely known to be a likely contender for the 2017 South Korean presidential election. He was selected as the People's Party's nominee, defeating Sohn Hak-kyu and Park Joo-sun. Despite rapid increase in opinion polling which briefly bypassed Moon Jae-In, Ahn floundered in TV debates that led to his loss finishing third in a field of five total candidates.

The underperformance of his presidential campaign and a party scandal that found People's Party members fabricating evidence to smear Moon Jae-in's campaign led Ahn to declare in July 2017 to both apologize and take a step back from politics in "self-reflection." He returned a month later to run, and later win, the party chairmanship.

Ahn remained in the NPAD, but came into increasing conflict with Moon Jae-in, who had taken over sole leadership of the party after his resignation, and the "pro-Roh" faction that Moon represented. In December 2015, Ahn issued an ultimatum to Moon demanding that a convention be held at the beginning of 2016 to elect a new party leader. Moon rejected the demand. Ahn then left the NPAD along with a range of other lawmakers opposed to Moon, including Kim Han-gil. Announcing that he would form a new party, he subsequently joined forces with Chun Jung-bae, who had left the party earlier in the year, to form the People's Party in January 2016. Moon resigned as leader after Ahn's defection, describing his experience as "a series of difficult days without a single one of respite".

Having entered the Assembly, Ahn began to explore the creation of a new party, which was provisionally named the New Political Vision Party on the basis of public surveys. On 26 March 2014, however, while the party was in the process of being set up, Ahn merged his faction with the liberal Democratic Party to form the New Politics Alliance for Democracy (NPAD), becoming co-chairman of the new party alongside Kim Han-gil. Ahn and Kim both resigned from their position three months later in July following the new party's disappointing performance in by-elections that year, which had seen the liberals lose a seat in Jeolla to conservatives for the first time in 26 years.

On 11 March 2013, Ahn announced that he would run for a seat in the National Assembly of South Korea as an independent candidate in the by-election in the district of Seoul Nowon C. He won the election on 24 April, entering his first elected office. In May 2013, he launched a new think tank named Policy Network Tomorrow.

He ran as an independent candidate for the presidential election in 2012, but withdrew a month before the election took place to support Moon Jae-in whom he ran against in 2017 as the People's Party nominee. He was a founding co-leader and the party leader of the People's Party until his party and Bareun Party merged as Bareunmirae Party in February 2018.

He alluded to standing as a presidential candidate in his 2012 book Thoughts of Ahn Cheol-Soo.

On 19 September 2012, at 3 p.m. Korea Standard Time, Ahn held a press conference and announced his intention to run for the 2012 presidential election. This announcement came after months of speculation on whether or not Ahn was going to run for the presidency. The South Korean presidential election was to be held on 19 December 2012. In an address that lasted around 20 minutes, Ahn spent a considerable amount of time explaining how he came to the decision to run for President of the Republic of Korea, quoting the people he had met while exploring his candidacy, who had expressed their desire for a "new politics". Ahn at one point showed to be polling stronger than Moon Jae-in, with a few polls showing he could win against Park Geun-hye, the candidate who would go on to win the election. On 23 November 2012, at 8:20 p.m. KST, Ahn announced that he would drop out of the race, endorsing Moon Jae-in, the Democratic United Party presidential candidate.

Ahn has also made appeals to conservatives, however, and has associated the People's Party with "reformative" currents of Korean conservatism. In September 2012, Ahn visited the graves of Syngman Rhee, Park Chung-hee, and Kim Dae-jung. Park and Rhee are often praised by Korean conservatives, and Kim by liberals. Ahn stated at the time that it would be "hypocritical to paint half the people as enemies and at the same time call for 'unity' ". Ahn has been considered "more palatable for conservative voters" in part due to his business background.

In September 2012, Ahn made a public apology as reports surfaced that his wife evaded taxes by under-pricing a 2001 apartment she bought worth ₩450 million to ₩250 million, thus reducing the acquisition and registration taxes by up to ₩10 million. However, a statement by the Korea Taxpayers' Association claimed that the "down contract" was in accordance with trade customs and thus not unlawful due to flaws in the local tax law between 1996 and 2005.

In early September 2011, speculation spread that Ahn would enter politics by competing in the 26 October Seoul mayoral by-election. The Democratic Party and Liberty Korea Party attempted to recruit Ahn for the mayoral by-election though they failed due to Ahn feeling like he, and many other voters, had become disenfranchised with the main two choices. Ahn eventually made an announcement, denouncing the opposition and ruling party and saying he was not sure on his candidacy, deciding to watch the polls before making a choice though he shared the sentiment that he felt like it'd take a lot of work to help Seoul, saying "ten years of work" would be needed to help the city.

In December 2011, Ahn has expressed his willingness to donate half of his shares in AhnLab for the education of children from low-income families. He owns 37.1 percent of AhnLab shares, and as of 9 December 2011, the value of the shares to be donated is about 250 billion won ($218 million).

Ahn was awarded an Executive Master of Business Administration (EMBA) degree from the Wharton School (San Francisco campus) in 2008. He then became a professor at KAIST in 2008, and later in the beginning of 2011 became the Dean of the Graduate School of Convergence Science and Technology at Seoul National University.

Since 2006, Ahn had been offered places in the main political parties but was constantly denied any chance to run as an independent due to opposing factions.

Ahn became an outside director of POSCO in 2005, and from 2010 to 2011 was chairman of the company.

The same company later became the largest computer security company in South Korea, and was included in annual lists of Korea's most admired companies by Korea Management Association Consulting between 2004 and 2008. He resigned as CEO in 2005 and served as chairman of the board until 2012.

In 1999, the company began to run a surplus after the CIH virus became widespread in Korea and people needed to buy V3 to protect against it. By the end of 1999, AhnLab, Inc became the second biggest computer security company in South Korea. That same year, he won the Scientist of the Year Award presented by the Korea Science Journalists Association.

Ahn, not knowing how to run a business at first, struggled for the first several years. Whilst managing the company, Ahn was also attempting to get a master's degree in engineering at the University of Pennsylvania, where he graduated in 1997. Ahn eventually received a $10 million offer from US software giant, McAfee and Ahn met with John McAfee personally. McAfee was struggling to expand into South Korea due to AhnLab, Inc and wanted to purchase the company in an attempt to monopolize the anti-virus software market in South Korea. Ahn rejected the offer because, despite AhnLab struggling, selling the company would lead to widespread redundancies and might allow a foreign firm to dominate the Korean market.

Prior to politics, Ahn founded AhnLab, Inc., an antivirus software company, in 1995. He was chairman of the board and Chief Learning Officer of AhnLab until September 2012, and remains the company's largest stakeholder. Prior to entering politics, Ahn served as dean of the Graduate School of Convergence Science and Technology at Seoul National University until September 2012.

After finishing military service as a medical officer in the South Korean navy, and leaving behind his career in the medical profession, Cheol-soo went on to establish his venture company AhnLab, Inc in March 1995 after being advised by a software company official to do so. Ahn had previously attempted to distribute V3 via Samsung's brand though Samsung rejected Ahn's offer.

In 1988 he married Kim Mi-kyung, who is currently a professor at the Seoul National University College of Medicine. Ahn has a daughter with Kim.

He received his Doctor of Medicine (MD), Master of Science (MS), and Doctor of Philosophy (PhD) degrees in physiology from Seoul National University between 1980 and 1991. He became the youngest chief of professors at Dankook University medical college at 27 years of age, marking his first career as a medical doctor. Ahn met his wife whilst in university.
