The Right Honourable Elizabeth Truss, known as Liz Truss, served a brief term as prime minister of the United Kingdom. She was appointed to the position on Sept. 6, 2022, and announced that she was stepping down on Oct. 20, 2022.

As prime minister, Truss oversaw the government of the U.K., including the civil service and the treasury in her joint roles as the minister for the civil service and first lord of the treasury, respectively. Truss was also minister for the union, charged with ensuring that the government works on behalf of the entirety of the U.K.

Truss succeeded former Prime Minister Boris Johnson, who served in the position from 2019 to 2022. She was succeeded by Rishi Sunak, who took over immediately after Truss resigned. Truss first entered Parliament in 2010 and is a member of the Conservative Party. She is the third female to serve as the U.K.’s prime minister.

Early Life and Education

Truss was born in Oxford, England, in 1975 to a family that was politically left wing. Her father was a junior research fellow in mathematics at Oxford University, and her mother was a nurse. Early in life Truss and her family moved to Paisley, Scotland, and then to Leeds, England. Truss and her family were politically active throughout.

Truss attended Merton College, Oxford, receiving a degree in philosophy, politics, and economics. At this time Truss was an active member of the Liberal Democrats Party and became known for a speech in 1994 at the age of 19 in which she called for the abolition of the monarchy. After graduating she joined the Conservative Party following a trip to newly free eastern Europe in 1990.

Following college Truss worked as a commercial manager at the oil and gas company Shell PLC (SHEL) and as economic director at telecommunications firm Cable & Wireless Communications Ltd. She was also deputy director at the Reform Research Trust.

Political Career Prior to Prime Ministership

Early Political Roles

Truss first ran as a parliamentary candidate in 2001, when she was the Tory candidate for Hemsworth, West Yorkshire. She was defeated in this election and again in a similar one in Calder Valley, West Yorkshire, in 2005. However, in 2006 she won election as a councilor in Greenwich, London.

By 2010 Truss had gained the attention of Conservative Party leader and future Prime Minister David Cameron, who advocated for her in her bid to be Conservative MP for South West Norfolk. Truss won the election despite the news emerging that she had an affair with a fellow Tory politician years earlier. In 2012 Truss gained attention for being a co-author of Britannia Unchained, a conservative political treatise that criticized British workers for laziness and called for improvements in education, among other things.

Cabinet Minister

In the years following her 2010 electoral victory, Truss attained a number of additional and increasingly prominent appointments. In September 2012 she was appointed parliamentary undersecretary of state for education and childcare, her first cabinet minister appointment. In this position Truss proposed a reform to Britain’s A-Level qualification exams and led a campaign to improve British math standards.

From 2014 to 2015 she served as secretary of state for environment, food, and rural affairs. She acknowledged the impact of climate change and launched a long-term strategy to boost the U.K.’s bee and pollinating insect population.

From July 2016 to June 2017 Truss was lord chancellor and secretary of state for justice, the first woman to hold either position. In these positions Truss drew criticism in 2016 for what some called a failure to adequately defend a group of judges who came under attack by other politicians and media outlets regarding a ruling pertaining to Brexit. Truss then became chief secretary to the treasury in 2017, a move seen by some as a demotion. She served in this position until July 2019. Truss supported Johnson in his bid for the position of prime minister in 2019.

Following his ascent to prime minister, Johnson appointed Truss the secretary of state for international trade in 2019. She also received a joint appointment as minister for women and equalities that year. In these positions Truss championed her support of free trade by introducing the Trade Act 2021 in Parliament, which established post-Brexit implementation of international trade agreements.

Truss was secretary of state for foreign, commonwealth, and development affairs from Sept. 15, 2021, until her accession to the post of prime minister. She became the U.K.’s chief negotiator with the European Union (EU) in December 2021.

Election to Prime Minister

On July 7, 2022, Johnson announced that he would resign as prime minister following a period of personal and political scandals. The Conservative Party engaged in a leadership election over the following two months, and Truss eventually beat rival Sunak in early September 2022 following several rounds of voting among members of Parliament. She was officially appointed prime minister on Sept. 6, 2022.

Policy Positions

Truss is known for her support of free market principles and traditionally liberal views on economic policy. She originally campaigned for the “Remain” side in the 2016 EU membership referendum but later said she supported the Brexit position. In her work in foreign policy, Truss developed a hawkish reputation, particularly for her dealings with Russia. Truss has supported efforts to reduce the impact of climate change, calling for a doubling down on the U.K.’s commitment to achieve net-zero greenhouse gas emissions by 2050.

Truss announced the Energy Price Guarantee shortly after becoming prime minister and amid anticipation of significant cost-of-living crises across Europe. The Energy Price Guarantee caps the price per unit for domestic energy supplies, putting a significant cost to the U.K. government of potentially up to £200 billion ($223.2 billion).

‘Trussonomics’

Truss’ approach to economic policy has earned the nickname “Trussonomics” from some analysts for its apparent similarities to Reaganomics, the policies favored by U.S. President Ronald Reagan in the 1980s. Reaganomics were notable for significant tax cuts, a decrease in social spending, and an increase in military spending. Proponents of Reaganomics suggest that its policies will have a trickle-down effect in which tax breaks for corporations and wealthy individuals should eventually benefit less wealthy taxpayers.

In September 2022 Truss and Chancellor of the Exchequer Kwasi Kwarteng announced sweeping tax cuts and increases in government borrowing. The British pound fell to its weakest level on record compared with the U.S. dollar following the announcement. After pushback from Conservative Party lawmakers, the government announced on Oct. 3, 2022, that it would no longer plan to abolish the top income tax rate for high earners, previously a key component of the initial economic plan. On Oct. 14, 2022, Truss fired Kwarteng and further reversed course from her initial plan, saying that she would not block an increase in corporate taxes. Kwarteng was replaced by Jeremy Hunt, a political moderate.

Brief Term as Prime Minister

Following just 45 tumultuous days in office, Truss announced on Oct. 20, 2022, that she would step down from her role as prime minister. Truss had trouble justifying the firing of Kwarteng, given that she had also been a vocal advocate of the tax cut plans that roiled the markets and sank the pound. In an attempt to reassure the markets, Hunt eliminated nearly all of Truss’ proposed tax cuts and limited the scope of the Energy Price Guarantee plan.

Having lost support within Parliament and the Conservative Party, Truss disclosed her intention to resign, making her the shortest-serving prime minister in the history of the U.K. Her departure set the stage for an emergency election to determine her replacement. Just a few days after Truss’ resignation, the Conservative Party announced that Sunak, a former banker, would take over as prime minister.

Opposition parties had called for a general election to be held right away, criticizing the shuffling of Tory politicians in and out of the top leadership role without allowing the public to have its say. However, as the Conservative Party had a majority in Parliament, its leader would automatically become prime minister without a general election. This is because a general election is not required to be called until five years after the start of a new Parliament, which in this case would be Jan. 28, 2025.

Thus, only members of the party were entitled to vote on who would replace Truss as prime minister. Sunak emerged as the only candidate to receive the backing of 100 senior lawmakers (out of 357), which is the threshold required to reach a potential party-wide runoff election. As there was no second candidate, the full party did not take a vote, meaning that a mere 100 or so people elected the next prime minister of the U.K.

Despite serving as prime minister for such a brief period, Truss is eligible to receive annual payments of £115,000—known as the Public Cost Allowance (PDCA)—for the remainder of her life. Opponents have called on Truss not to accept the allowance given her short time in office.

The Bottom Line

Liz Truss was appointed prime minister of the United Kingdom on Sept. 6, 2022, succeeding Boris Johnson. On Oct. 20, 2022, she announced that she was stepping down from the role, making Truss the shortest-serving prime minister in the nation’s history. Rishi Sunak took over as prime minister following Truss’ resignation. Truss is a member of the Conservative Party and has held parliamentary or cabinet positions in the U.K. since 2010. Politically, she is known for her support of free market principles, a hawkish approach to foreign policy, a series of crusades in favor of education reform and reduced taxes, and her advocacy of “Trussonomics,” a belief system akin to supply-side or trickle-down economics.
