Liz Truss was elected as the British Conservative Party’s new leader and the country’s new prime minister on Monday.

Currently the foreign secretary, Truss will take office on Tuesday when Queen Elizabeth II formally appoints her as prime minister of the United Kingdom.

Instead of at Buckingham Palace in London, the ceremony will take place at the queen’s Balmoral Estate in Scotland, where the monarch is spending her summer.

Truss, 47, defeated former Treasury Chief Rishi Sunak in a leadership election in which only about 170,000 Conservative Party dues-paying members were allowed to vote. Reuters reported Truss received 81,326 votes; Sunak received 60,399.

The new prime minister is under immediate pressure to deliver on her promises to address the UK’s cost-of-living crisis and an economy heading into a potentially prolonged recession.

Thousands of workers have gone on strike demanding higher pay to keep up with rising costs.

For the first time since the 1980s, inflation has risen above 10%, and the Bank of England expects it to reach a 42-year high of 13.3% in October. This is primarily due to rising energy costs, which will increase by an average of 80% beginning next month.

Truss won the support of many Conservatives with her determination to reduce state intervention and cut taxes. Both she and her opponent Sunak have expressed admiration for Margaret Thatcher, prime minister from 1979 to 1990, and her free-market, small-government economic policies.

But it is unclear how Truss’ right-wing brand of conservatism, which played well with party members — who account for far less than 1% of the adult population in the UK — will be received by the wider British public, particularly those most suffering from the inability to afford necessities like heating their homes this winter.

“I will deliver a bold plan to cut taxes and grow the economy, and I will deliver on energy bills,” Truss declared to party members after her election.

While the Conservative Party members wanted that tax-cutting message, “The country, I would guess, (wanted it) less so,” said Bronwen Maddox, director of London’s Chatham House think tank.

“Right now, you’ve got people deeply rattled, many of whom are very, very afraid of going into a year where all they can see is rising costs.” Maddox elaborated. “I don’t think she has a claim to the country’s popularity until she gets an answer on that.”

Truss had promised to act “immediately” to address rising energy costs but has so far not provided any details.

Truss will be the fourth Conservative prime minister in six years, succeeding Boris Johnson, Theresa May, and David Cameron.

Johnson resigned due to a series of ethics scandals, which culminated in July with the resignation of dozens of cabinet ministers and lower-level officials in protest of his handling of sexual misconduct allegations against a senior government member, according to CBC News.

The two-month leadership election left Britain in a power vacuum during which the country’s discontent grew as energy and food prices skyrocketed.

Truss and Sunak were both key members of Johnson’s Cabinet, though Sunak resigned in the final days of Johnson’s office.

According to Steven Fielding, a professor of political history at Nottingham University, a Truss government may not sit well with many voters because it reminds them too much of Johnson’s misdeeds. “She’s been elected by Conservative members as Boris Johnson 2.0,” he said.

Truss has made it very clear that she is a loyal Boris Johnson supporter, Fielding added. “I think she’ll find it difficult to separate herself from the entire Johnson shadow.”

The center-right Conservative Party was allowed to hold an internal election to select a new party leader and prime minister without going to the broader electorate under Britain’s parliamentary system of government. A general election will not be required until December 2024.

Truss and Sunak were the final two candidates chosen from a field of 11.
