Ulf Hjalmar Kristersson (born 29 December 1963) is a Swedish politician who has served as Prime Minister of Sweden since October 2022, and since 17 September 2026 in a caretaker capacity, following the defeat of his governing bloc in the September 2026 general election. He has been the leader of the Moderate Party since 2017. He has been a member of the Riksdag since 2014, having previously served from 1991 to 2000, and was Minister for Social Security from 2010 to 2014.
Kristersson became party leader after Anna Kinberg Batra resigned in 2017. Following the 2022 Swedish general election, he formed the minority Kristersson cabinet consisting of the Moderates, the Christian Democrats and the Liberals, supported by the Sweden Democrats through the Tidö Agreement. The four parties held 176 of the Riksdag's 349 seats, and Kristersson was elected prime minister on 17 October 2022.
As prime minister, Kristersson completed Sweden's accession to NATO, increased defence spending, expanded support for Ukraine and pursued a more restrictive migration policy. In 2024, the number of asylum-related residence permits fell to its lowest level since 1985. His government also expanded preventive police powers; shootings in Sweden fell from 390 in 2022 to 147 in 2025.
Kristersson has been praised for Sweden's NATO integration, increased defence expenditure and support for Ukraine, while critics have focused on his reliance on the nationalist Sweden Democrats, tighter migration policies and a climate policy assessed as insufficient to meet several targets.
Biography Early life Ulf Kristersson was born in Lund, Skåne County, as the eldest of three children to Lars Kristersson (1937–2015) who worked with economics and teacher Karin Kristersson (née Axelsson; 1939–2020). The family moved to Torshälla outside Eskilstuna five years later. In his youth, Kristersson was a troupe gymnast. Kristersson finished secondary school at S:t Eskils gymnasium in Eskilstuna. After graduating, Kristersson did military service as a platoon commander in the Uppland Regiment from 1983 to 1984 and completed a degree in economics at Uppsala University.
Early political career In connection with the 1985 Swedish general election, he was employed as a campaigner at the Moderate Youth League (MUF) in Sörmland. On 26 November 1988, he rose to become the new Chairman of MUF, succeeding Beatrice Ask. In 1991, the centre-right Bildt Cabinet took power, and Kristersson became an MP. He served on the Social Security Committee. He soon becomes a vocal critic of the government's crisis agreement with Social Democrats. At the time, Kristersson developed a friendship with the former party leader, Gösta Bohman, who, in some respects, also supported his criticism of the Bildt Cabinet.
In 1992, Kristersson was challenged as chairman of MUF by Fredrik Reinfeldt. The congress was preceded by considerable ideological divisions between liberals and conservatives. All this erupted at the congress in Lycksele, which came to be known as the Battle of Lycksele. Kristersson, the liberal alternative, lost narrowly. It is said that his loss caused his withdrawal from front-line politics and he was subsequently known as part of the "Lost Generation" of the Moderate Party. At the time, he was criticised for his amateurism and preference for communication over political thought.
From 1995 to 1998, Kristersson was chief of marketing at Timbro, a free market think-tank, while also working in parliament. In 1994 he also released the book Non-working Generation at Timbros publishing company. In the book Kristersson argues against the welfare institutions in Sweden and compares these to apartheid because he considered these institutions to force people into passivity.
Career outside politics Kristersson left his parliamentary seat in April 2000, feeling that the new party leader Bo Lundgren had declined his services. Kristersson worked for two years in the private sector, mainly as communications director and VP for the internet consultancy Adcore, a dotcom crash casualty.
Kristersson was chairman of the Swedish Adoption Centre (). During his time as chairman, information emerged that the centre handled adoptions of children trafficked from China.
Municipal politics He returned to active politics in 2002 as Commissioner (Mayor) for Finance in Strängnäs and served there until 2006. In 2006, he was appointed Vice Mayor () in Stockholm, responsible for the social welfare and labor division.
During this time Kristersson got a rental contract for a five-room apartment in central Stockholm from . Ersta Diakoni describes its basic purpose as "to be a support for people in vulnerable situations, to take social responsibility and to offer care." Due to that, Stockholm city was contracting and gave economical aid to Ersta Diakoni, that, among other things provided for housing for those in social need. An investigation was started and Kristersson and another person in the associations leadership were suspected of bribery. According to an internal policy document, the apartments in the building were reserved for those newly employed by the association and students at Marie Cederschiöld högskola. The investigation was closed with the motivation that Kristersson did not have direct influence over the aid that the association could give.
Fredrik Reinfeldt also asked Kristersson to lead the committee responsible for developing a new family policy for the party. He immediately caused controversy by suggesting that fathers must take a month of paternity leave for the family to receive all benefits. This was clearly conflicted with traditional Moderate Party policy, which has centred on individual choice.
Return to national politics On 5 October 2010, Fredrik Reinfeldt appointed Kristersson to become Minister of Social Security, a position he held for four years. After the 2014 Swedish general election, the Reinfeldt cabinet resigned, but Kristersson was elected as MP again, this time for Södermanland County. Following Reinfeldt's resignation as party leader, Anna Kinberg Batra appointed him as Shadow Finance Minister.
Leader of the Moderate Party
Anna Kinberg Batra resigned as leader of the Moderates on 25 August 2017, after internal criticism. Kristersson publicly decided to run for leadership on 1 September and was elected on 1 October. The party saw a sharp increase in support in the polls, compared to the record low numbers under his predecessor Batra. He has a harsher stance against immigration than his predecessors.
2018–2019 government formation
In September 2018, incumbent Prime Minister Stefan Löfven was ousted. Kristersson expressed hope of becoming the next prime minister. On 2 October, he was designated by Speaker of the Riksdag Andreas Norlén to form a new government.SVT: Ulf Kristersson (M) får uppdraget att försöka bilda regering, 2018-10-02 (in Swedish) He initially sought to form a government coalition involving the Alliance parties (Moderate Party, Centre Party, Christian Democrats and Liberals) with support from the Swedish Social Democratic Party (S). On 9 October, he said that S had rejected all further talks on agreements and that he would now seek other ways to form a new government. On 14 October, he stated that he was not able to form a new government.Aftonbladet: "Ulf Kristersson ger upp försöken att bilda regering", 2018-10-14 , läst 14 October 2018 (in Swedish)
On 5 November 2018, Speaker Norlén proposed Kristersson as prime minister following breakdowns in all other government negotiations.Ulf Kristersson proposed as new Prime Minister by the Speaker , 5 November 2018] (in Swedish) On 14 November 2018, the Riksdag rejected Kristersson's bid to become prime minister by a vote of 195 to 154. It was the first time ever that a speaker's proposal for Prime Minister lost such a vote and the first time in 40 years that centre-right parties (Centre Party and Liberals) vetoed a centre-right candidate for Prime Minister.
2019–present Kristersson held a meeting in December 2019 with Jimmie Åkesson, leader of the Sweden Democrats, and said that he would cooperate with them in parliament. The anti-immigration party had previously been subject to a cordon sanitaire by all other parties, with Kristersson himself ruling out dialogue with them ahead of the 2018 elections. According to Ann-Cathrine Jungar of Södertörn University, this put Sweden in line with several other European countries in which centre-right and radical-right parties cooperate. In August 2020, he criticised the government for a perceived failure to deal with rising crime, including gun violence, which he called a "second pandemic".
2021 government crisis
On 29 June 2021, after Prime Minister Stefan Löfven was ousted, Speaker of the Riksdag Andreas Norlén formally tasked Kristersson with forming a government. Kristersson had until 3 July to report his potential government to Norlén. Kristersson planned to lead a coalition of his own party along with the Christian Democrats, Liberals, and Sweden Democrats. On 1 July, Kristersson informed the Speaker that he did not have enough support to form a government and returned his mandate.
2022 government formation
Kristersson led the Moderate Party (M) during the 2022 campaign, in which his party lost parliamentary seats, as well as the second-place position (for the first time since the 1976 Swedish general election); nonetheless, the right-wing bloc gained an absolute majority, resulting in Magdalena Andersson's resignation and Kristersson's nomination as prime minister by Speaker Andreas Norlén. Kristersson signalled his preference for a coalition government between M, the Christian Democrats (KD) and Liberals (L) with external support from the Sweden Democrats (SD).
On 14 October, Kristersson presented the fully documented Tidö Agreement () between M, KD, L and SD. This enabled the first three parties to seek a mandate for a new national administration to be chosen by the Riksdag, with SD given strong influence amounting to confidence and supply. On 17 October, Kristersson was elected prime minister by 176 Riksdag votes for, and 173 votes against him, with no absentees or abstentions. It is the first time SD has exerted direct government influence. European Union lawmakers criticised the center-right and the Moderate Party in particular, as a member of the European People's Party, for allying with the far right, as did opposition leaders.
The joint programme places particular emphasis on fighting crime, reducing immigration and reviving nuclear energy. The quota of refugees accepted each year would be drastically reduced from 6,400 to 900. The new authorities are also planning deportations for "bad behaviour". In terms of security policy, there is talk of authorizing searches in the absence of suspicious behaviour in certain neighbourhoods deemed sensitive, increasing the penalties and opening up the possibility of anonymous testimony in court. A national ban on begging will be tested. The agreement also provides for a downward revision of Sweden's greenhouse gas emission targets, a reduction in development aid and possible privatization.
With 19.1% of the vote for his party, Kristersson is the prime minister with the smallest amount of the vote since 1978. He began his term of office with a significantly lower popularity rating than that of the outgoing Prime Minister Magdalena Andersson.
Prime Minister of Sweden (2022–present)
On 18 October 2022, Kristersson as per constitutional requirements, was officially identified by King Carl XVI Gustaf as the new Prime Minister during a meeting of the Council of State, having announced his government program earlier that day in a speech to the Riksdag as well as having appointed the ministers of his cabinet.
