British media reports said that the "Chief Whip" responsible for group discipline and her deputy had resigned in protest at an abrupt departure from the government's initial demand for uniform voting behavior by Tory MPs. Downing Street was finally forced to take the unusual step late in the evening, with a statement clarifying that the two whips were still "in office".

Opposition Labor MP Chris Bryant called for an official inquiry after the vote. Before the vote, he saw that Tory MPs in Parliament had been massively harassed and pressured, Bryant said.

Truss has only been in office since the beginning of September. Nevertheless, she is already under massive pressure in her own party. Secretary of the Interior Braverman submitted her resignation on Wednesday. In her resignation letter, she expressed "serious concerns" that Truss was breaking her campaign promises.

Truss again declined to resign before Parliament. She was "a fighter and not a shirker," she said. Truss had been criticized for not resigning herself because of the fiasco surrounding her tax plans, but for forcing her finance minister, Kwasi Kwarteng, to resign.

Due to a lack of counter-financing, the tax cut package had led to turbulence on the financial markets and to severe resentment in the ranks of the governing party. As a result, Trump initially instructed then-Finance Minister Kwarteng to withdraw a particularly controversial tax cut for top earners. She released him on Friday. The new Treasury Secretary Jeremy Hunt then almost completely overturned the planned financial package on Monday.
