John Steenhuisen

John Steenhuisen (born March 25, 1976, Durban, South Africa) is a South African politician who has served as deputy minister of trade, industry, and competition since 2026. He previously served as South Africa’s minister of agriculture (2024–26). Steenhuisen is a member of the Democratic Alliance (DA), the country’s leading opposition party, and previously served as the DA’s federal leader (2019–26).

Early life and family

Steenhuisen grew up in Durban, in what was then the province of Natal (now part of KwaZulu-Natal). He attended Chelsea Drive Senior Primary and then Northwood Boys High School, graduating from the latter in 1993. Steenhuisen and his first wife, Julie, were married in 2000 and have two daughters together. The couple divorced in 2010 after he was revealed to have had an affair with Terry Kass Beaumont, whom he later married, in 2014; they have one daughter together.

Entry into politics and ascendancy

Steenhuisen became involved with the Democratic Party (DP) during the 1990s, assisting with the distribution of the party’s campaign materials. In 1999, when he was only 22 years old, he was elected to serve as the councillor representing the Durban North constituency in the Durban city council. He was elected the next year to serve in its successor, the eThekwini metropolitan municipality council, and served until 2009.

Meanwhile, in 2000 the DP joined with two other parties to form the Democratic Alliance (DA), with which Steenhuisen was active. In 2009 he was elected under the DA’s banner to serve in KwaZulu-Natal’s provincial legislature. He was also named the DA’s caucus leader in the legislature and the DA’s provincial leader. He resigned from the latter position in 2010, however, after his affair with Kass Beaumont—the party’s provincial spokesperson, who was married to Michael Beaumont, the DA’s provincial director—came to light.

In 2011 Steenhuisen moved to the federal level of government, becoming a member of the National Assembly; he retained his National Assembly seat after the 2014 and 2019 elections. From 2014 to 2019 Steenhuisen served as the chief whip of the official opposition. He became known for his fiery speeches and debate skills, especially in regard to fellow members of parliament from the ruling African National Congress (ANC) party as well as the Economic Freedom Fighters (EFF) party.

Federal leader of the Democratic Alliance

In 2019, Steenhuisen was elected to be the interim federal leader of the DA following the resignation of Mmusi Maimane from the position. Steenhuisen was formally elected to the post at the party’s federal congresses in 2020 and in 2023.

In 2023, in preparation for the next year’s elections, Steenhuisen spearheaded the formation of the Multi-Party Charter for South Africa (MPC), a coalition of political parties with the goal of unseating an increasingly vulnerable ANC, which has been in power since the country’s first free elections in 1994. The coalition stemmed from a suggestion he made at the DA’s federal congress in April 2023 for a “moonshot pact,” in which similar-minded organizations would put aside their individual party agendas and unite in the best interests of the country. In addition to the DA, other parties in the coalition included the Inkatha Freedom Party (IFP), Freedom Front Plus, and ActionSA. Steenhuisen also warned of the potential for what he referred to as “doomsday coalition,” comprising the ANC and EFF, which he claimed would lead to a “calamitous outcome.” He later added the nascent uMkhonto weSizwe Party (MK) to his discussion of a doomsday coalition.

The first national and provincial elections for the party under Steenhuisen’s leadership were held on May 29, 2024. In the national election, the DA won almost 22 percent of the vote—a slight uptick from the previous election—and the party finished second behind the ANC. In the government of national unity that the ANC formed with the DA and other parties, Steenhuisen was named minister of agriculture. He took office on July 3, 2024.

During Steenhuisen’s time as minister of agriculture, an outbreak of the highly contagious foot-and-mouth disease, dating back to 2021, intensified in 2025 and 2026, spreading among herds across the country and threatening the livestock industry. He faced growing criticism over the government’s actions to contain the disease.

In February 2026 Steenhuisen announced he would not stand for another term as the DA’s federal leader. He was succeeded in that post by Geordin Hill-Lewis at the party’s federal congress in April 2026.

2026 cabinet shuffle

Hill-Lewis requested that South African Pres. Cyril Ramaphosa make changes to the DA-held cabinet positions in June 2026. Among the changes was a move that saw Steenhuisen leaving his post as minister of agriculture to serve as deputy minister of trade, industry, and competition. Steenhuisen assumed his new post on July 1, 2026.
