Taking out the 10 days of mourning for Queen Elizabeth II, Truss had only a week in control of events before her political programme imploded.
“That is the shelf-life of a lettuce,” The Economist magazine commented this week.
July 7 – Johnson announces his resignation after months of scandal, starting a leadership race in the ruling Conservative party.
After five rounds of voting by Tory MPs, Truss scrapes into the final run-off against frontrunner Rishi Sunak.
The pair take their case to grassroots members, where Truss’s hardline, right-wing platform proves more popular.
September 5 – Truss wins the Tory members’ vote by 81,326, against 60,399 for Sunak.
As the new leader of the largest party in parliament, that makes her prime minister — with support from less than 0.2 percent of the UK electorate and only a minority of her own MPs.
The next day, she is confirmed as prime minister by the queen.
Despite her weak mandate, Truss purges all Sunak supporters from her new cabinet, and installs the like-minded Kwasi Kwarteng as chancellor of the exchequer.
September 8 – Truss unveils a costly scheme to cap household energy bills, in response to Russia’s invasion of Ukraine.
But the dramatic announcement is eclipsed by the queen’s death, which suspends all government business for 10 days.
Truss joins King Charles III on a UK-wide tour, denying she is seeking to make political capital out of the mourning period.
September 23 – Kwarteng announces a “mini-budget” which details the price of the energy scheme — £60 billion ($67 billion) over the next six months.
But there are no measures to raise funds.
Instead, he announces massive new borrowing to pay for sweeping tax cuts — including for top-earners — along with scrapping a cap on bankers’ bonuses.
The announcement immediately draws political fire for being unfair. But the markets reserve the most stinging verdict in response to the new borrowing — driving the pound down towards parity against the dollar.
Two days later, a Sunday, Kwarteng vows “more to come” on tax cuts. The next day, when markets reopen, the pound plumbs new depths.
The budget is dubbed “Kami-Kwasi” by media, which begin reporting tensions between Kwarteng and Truss, and deep disquiet among Tory MPs including cabinet ministers.
September 28 – With bond market turmoil placing British pension funds in jeopardy, the Bank of England announces a two-week programme to buy long-term UK bonds, capped initially at £65 billion, “to restore orderly market conditions”.
September 29 – Pollsters YouGov report a 33-point lead for the opposition Labour party over the Tories — its biggest margin since the heyday of former Labour prime minister Tony Blair in the late 1990s.
Other polls also point to electoral disaster for the Conservatives. But hours before his keynote speech at the party’s annual conference at the start of October, Kwarteng vows to “stay the course”.
October 3 – Kwarteng and Truss are forced into a humiliating U-turn as civil war engulfs the conference, scrapping the planned cut in the top rate of income tax following hurried late-night talks.
In her own conference speech on October 5, Truss vows to pursue her “growth, growth, growth” agenda but fails to assure party rebels and nervous markets.
The UK government bond yields keep rising, inflicting more pain for UK households as mortgage rates surge.
October 10 – In another volte-face, Kwarteng reveals he will publish a medium-term fiscal plan alongside independent budget forecasts on October 31 — Hallowe’en — rather than late November.
The plan is expected to lay out how the government will balance the books.
But on October 12, Truss rules out any cuts to public spending, even as she vows no further U-turns on the remaining tax cuts, compounding perceptions of a government in chaos.
