LONDON (AP) — British Prime Minister Liz Truss has only been in office for six weeks. But already her libertarian economic policies have triggered a financial crisis, emergency central bank intervention, multiple U-turns and the firing of her Treasury chief. Now Truss faces a mutiny inside the governing Conservative Party that leaves her leadership hanging by a thread. Conservative lawmaker Robert Halfon accused the government Sunday of treating the country like “laboratory mice on which to carry out ultra, ultra free-market experiments.” Conservatives are mulling whether to try to force out their leader. Truss, meanwhile, has appointed a new Treasury chief, Jeremy Hunt, who plans to rip up much of her economic plan when he makes a budget statement Oct. 31.
