Chancellor Jeremy Hunt has insisted Liz Truss is still in charge of the government, after a series of U-turns left her premiership in jeopardy. Some Tory backbenchers have been talking privately about how to remove the PM, after market turmoil led her to abandon her flagship tax policies. Hunt urged the party to unite behind her, as the pair held crunch talks to thrash out plans on tax and spending. But a senior Tory MP said "the game is up" and called for Truss to go. Hunt replaced Kwasi Kwarteng on Friday, after the former chancellor was fired following financial turbulence in the wake of last month's mini-budget and a backlash from a number of MPs in his party. In a bid to restore market confidence, Truss has junked key parts of the tax-cutting blueprint that was unveiled by Kwarteng and won her the Tory leadership contest, putting her into office. Measures already jettisoned from the £45 billion package of unfunded tax cuts announced last month include scrapping the top income tax rate, and a freeze in corporation tax. And Hunt, who held talks with Truss at her official Chequers country retreat earlier, has not ruled out further U-turns as he seeks to restore UK economic credibility. In an interview with Laura Kuenssberg recorded on Saturday, he said he was not "taking anything off the table". He warned of "difficult decisions both on spending and on tax," as he prepares to deliver an economic statement on Oct. 31 to reassure investors he has a plan to get public debt under control. However, there are newspaper reports that some Tory MPs have already begun talks about how to remove her from power, despite current party rules preventing a formal leadership challenge for a year. Tactics reportedly under consideration include submitting no-confidence letters in a bid to force party bosses into a rule change, or changing party rules to allow MPs to bypass members and pick a new leader themselves. Asked whether she could survive as PM, former minister Crispin Blunt told Channel 4: "No, I think the game is up and it's now a question as to how the succession is managed. "If there is such a weight of opinion in the parliamentary party that we have to have a change then it will be effected." Speaking to Sky News, senior backbencher Robert Halfon said, "Of course, colleagues are unhappy with what is going on." He added, "We're all talking to see what can be done about it". He said he was not calling on Truss to go, but called for a "dramatic reset" in the government's direction. And in a blistering attack, he accused ministers of behaving like "libertarian jihadists" treating the public as "laboratory mice on which to carry out ultra, ultra free market experiments". However Sir Geoffrey Clifton-Brown, who sits on the committee that decides the rules, told BBC Radio 4's Broadcasting House removing Truss would be a "very serious event". "We will only change the rules if it is very clear that a large majority, by which I mean probably sixty to seventy percent," he added. Meanwhile, in a further blow to the prime minister, US President Joe Biden has criticized tax cuts from her mini-budget. In an unusual intervention, he told reporters during a campaign visit that the outcome was "predictable" and "I wasn't the only one that thought it was a mistake". He added that he had disagreed with "the idea of cutting taxes on the super wealthy", but it was up to the UK to "make that judgment, not me". In his BBC interview, Hunt said every government department would be asked to make savings, ahead of the Oct. 31 economic statement. However, he insisted the changes would not be "anything like" the period of austerity which began in 2010, when predecessor George Osborne oversaw large cuts in public spending. Despite the U-turns, Hunt insisted Truss remained committed to her goal of promoting economic growth, but she had changed "the way we're going to get there". "She's listened, she's changed, she's been willing to do that most difficult thing in politics which is to change tack," he added. According to reports, Truss is also preparing to delay by a year her 1p cut to the basic rate of income tax. The Treasury has not confirmed the reports, adding: "We cannot speculate on any tax changes outside of a fiscal event." Former Health Secretary Matt Hancock urged the prime minister to reshuffle the Cabinet to extend her support across the party. He told the BBC: "There's a huge amount of talent on the backbenches — I'm not talking about me, but there are many others that should be brought into government." Labour's shadow business secretary Jonathan Reynolds said any further public spending cuts would be "entirely because" of government "incompetence". "I'm not even sure what this government's economic policy is at the moment. I don't know which bits of the budget still apply, and I don't know what we will hear next week," he said. — BBC
