But after a decades-long transformation that has seen her personal views change enormously, many will be asking what exactly Britain’s new leader stands for.
Many who have observed her over the years question whether she has any sincere beliefs at all, or if she simply endorses whatever is the most convenient at the time.
To say that Truss, 47, has been on a political journey would be an understatement. She was born in 1975 into a family that she herself has described as “to the left of Labour,” Britain’s main left-wing party. She grew up in parts of the UK that didn’t traditionally vote Conservative, moving between Scotland and the north of England.
In contrast with her privately educated cabinet colleagues, Truss went to a state school in the Yorkshire city of Leeds, and later won a place at Oxford University. There she was an active member of the Liberal Democrats, a centrist opposition party that has long been an effective opponent to the Conservatives in large parts of England.
Truss says she joined the Conservatives in 1996, just two years after she gave a speech at a Liberal Democrat conference calling for the end of the monarchy.
Even during her time as a Liberal Democrat, her peers questioned her sincerity and spotted traits that they say they still see in her today.
“I honestly think she was playing to the gallery back then, whether she was talking about decriminalizing drugs or abolishing the monarchy,” Neil Fawcett, a Liberal Democrat councilor who campaigned with Truss in the 1990s, told CNN. “I think she is someone who plays to the gallery with whatever audience she is talking to, and I genuinely don’t know if she ever believes anything she says, then or now.”
Truss has certainly continued to capture the attention of her audience. Since joining the Conservatives and becoming a lawmaker, she has fervently supported almost every conceivable ideology. She served loyally under three prime ministers in several different cabinet jobs, most recently as foreign secretary.
Most notably, she supported remaining in the European Union in the UK’s referendum in 2016. At the time, Truss tweeted that she was backing those who wanted to remain in the bloc because “it is in Britain’s economic interest and means we can focus on vital economic and social reform at home.”
Truss now backs Brexit, saying that her fears before the referendum that it could cause “disruption” were mistaken.
There is a debate within the Conservative Party as to how real this support of Euroskepticism is. Some think Truss was reluctantly following government orders, which opposed Brexit, in 2016. Others find that argument inconceivable.
Anna Soubry, a former Conservative cabinet minister and anti-Brexit campaigner, told CNN that Truss “had the most cover out of any of us to support Brexit. Her brief at the time included the farming community, who supported Brexit on the whole. I sat around the cabinet table and heard everyone’s reason for doing what they did and find it hard to believe she’s changed her mind quite this much.”
On the other hand, Gavin Barwell, who served as former Prime Minister Theresa May’s chief-of-staff, said that, after the Brexit vote, “Truss made a decision very quickly that there wasn’t room for a compromise. If you were to do it, it needed to be done fully. And as the stalemate dragged on, she argued that a binary choice was coming between leaving with no deal and Brexit being reversed, and the latter would be catastrophic for the government.”
The closer she has edged to power, the more Britons have wondered what a Truss premiership would look like. She has campaigned to lead on the most conservative of agendas. She has pledged to slash taxes from day one, tear up EU regulations and encourage private sector growth with low corporation tax. She has said she will not impose a windfall tax on energy companies despite their posting huge profits during the current cost-of-living and energy crisis.
These sorts of policies were, of course, red meat to the Conservative members who ultimately voted for her. And while some of those who know her question how much she actually believes in them, there is little doubt she will put her full effort into implementing them and making her impact immediately felt.
It’s possible that a Truss government will ultimately look a lot like Johnson’s, but with a greater emphasis on cutting taxes, shrinking the state and, potentially, an even harder line on Europe.
Critics have said the tax cuts she’s promised would lead to even greater inflation and rises in interest rates amid a forecast recession. Questions were also raised over a pledge Truss made to cut public sector pay, allegedly saving the public $8.8 billion. Her economics were questioned by her critics, and the uproar over perceived callousness toward public sector workers forced Truss to U-turn.
Julian Glover, a journalist and speech writer to former Prime Minister David Cameron, was a university contemporary of Truss and remembers traits in her that are still recognizable today: determined but unfocused.
“We only passed each other briefly and she was in a different year to me, but despite that, she stands out in my memory as a sort of strange, unfocused force, hugely in favor of action and change,” Glover told CNN. “It was always hard to see the aim of it all, or where it might lead, except that she would be at the center of it.”
Roger Crouch, who succeeded Truss as president of Oxford University Liberal Democrats, told CNN that he remembers a woman who was “determined, single-minded and willing to challenge orthodox and prevailing, often male, wisdom.”
Unlike many of those who knew Truss in her younger years, Crouch, who is now a teacher, thinks her opinions haven’t changed a huge amount since the 90s. “Liz was always more of a privatizing, libertarian liberal so there is a consistent thread of thought there. I remember a student discussion group in which she advocated privatization of lamp posts.”
Prime Minister Truss will have a hard time uniting her party, which has been in power for 12 years and has been bitterly divided over Brexit for six of them.
She will also have to lead the country through its worst cost-of-living crisis in decades. Inflation is at a 40-year high, energy bills are set to increase by hundreds, possibly thousands, of pounds a year, and the UK is forecast to enter a recession before the end of the year.
In July, inflation rose above 10% for the first time in 40 years, driven largely by the rising cost of energy, food and fuel. According to the Bank of England, inflation will soar to 13% by the end of the year. The central bank also predicted that the UK will enter a recession before the end of 2022.
Analysts are skeptical that Truss’ tax-cutting policies will do much to help citizens. The Institute for Fiscal Studies, an independent research group focusing on public finances, said last month that the leadership contestants, who were both promising tax cuts and lower government spending, “need to recognise this even greater-than-usual uncertainty in the public finances.”
This winter, many families will have to make a grim choice between heating their homes and eating. And for a party that has been in power for more than a decade, it’s hard to deflect the blame for that onto anyone else.
Her supporters see the chance for a fresh start in Truss. They believe that with Brexit less in the spotlight and the scandals that led to Johnson’s downfall soon to be a distant memory, the party will turn its focus to remaining in power and winning a historic fifth consecutive general election.
For her detractors, it is more complicated. During this leadership contest those who have supported her rivals feel they have been unfairly maligned simply for disputing that Truss should be handed the keys to Downing Street.
And for all Truss’ determination and single-mindedness, she takes over a party torn apart by infighting and suffering in the polls during a domestic crisis. So she may find her key objective — making her party electable at the next general election after so many years in power — too hard a task to achieve.
