LONDON >> British Prime Minister Liz Truss faces a House of Commons grilling today from a hostile opposition — and her own furious Conservative Party — as she tries to fend off calls to quit over her botched economic plan.

Truss is set to attend the weekly Prime Minister’s Questions session two days after newly appointed Treasury chief Jeremy Hunt ripped up the tax-cutting package unveiled by the prime minister’s new government less than a month ago.

The package of unfunded tax cuts announced Sept. 23 sparked turmoil on financial markets, hammered the value of the pound and increased the cost of U.K. government borrowing. The Bank of England was forced to intervene to prevent the crisis spreading to the wider economy and putting pensions at risk.

Under intense political and economic pressure, Truss last week fired her ally Kwasi Kwarteng as Treasury chief, replacing him with Cabinet veteran Hunt. On Monday Hunt scrapped almost all of Truss’ tax cuts, along with her flagship energy policy and her promise of no public spending cuts. He said the government will need to save billions of pounds and there are “many difficult decisions” to be made before he sets out a medium-term fiscal plan on Oct. 31.

Foreign Secretary James Cleverly urged Conservatives to give Truss another chance, saying “mistakes happen.”

“What you’ve got to do is recognize when they’ve happened and have humility to make changes when you see things didn’t go right,” he said.

Official figures released today showed U.K. inflation rose to 10.1% in September, returning to a 40-year high first hit in July, as the soaring cost of food squeezed household budgets. While inflation is high around the world — driven up by Russia’s invasion of Ukraine and its effect energy supplies — polls show most Britons blame the government for the country’s economic pain.

With opinion polls giving the opposition Labour Party a large and growing lead, many Conservatives now believe their only hope of avoiding electoral oblivion is to replace Truss. But she insists she is not stepping down, and legislators are divided about how to get rid of her.

Under Conservative Party rules, Truss is safe from a leadership challenge for a year, but the rules can be changed if enough lawmakers want it. Some Conservative legislators also believe Truss could be forced to resign if the party agrees on a successor.

As yet, there is no front-runner. Truss’ defeated Conservative leadership rival Rishi Sunak, House of Commons leader Penny Mordaunt and popular Defense Secretary Ben Wallace all have supporters, as does Hunt, who many see as the de facto prime minister already.

Some even favor the return of Boris Johnson, who was ousted in the summer after becoming enmeshed in ethics scandals.

Cleverly said he understood why colleagues were angry, but added: “That’s an emotional response, it’s not a plan.”

“What I’m not convinced by — far, far from convinced by — is that going through another leadership campaign, defenestrating another prime minister, will either convince the British people that we’re thinking about them rather than ourselves, or convince the markets to stay calm and ensure things like those bond yields and gilt yields start coming back down,” the foreign secretary told Sky News.
