The latest manifestation of neoliberalism, Trussonomics, reflecting a combination of the surname of the former British Prime Minister, Liz Truss, and her economic policies, has collapsed spectacularly in the United Kingdom. Ms. Truss, from the right wing of the Conservative Party, defeated Rishi Sunak, a moderate former Chancellor of the Exchequer (Finance Minister), in a bruising battle for support among approximately 170,000 Conservative Party members for Leader of the Party from which Boris Johnson, Prime Minister and Party Leader, had resigned after a series of scandals. Her defining policy proposal was to trigger growth of the British economy by reducing taxes on big business and the wealthy. Ms. Truss won and was sworn in as Prime Minister on 6 September. Her mandate was from the Conservative Party, not the electorate.
