Borrowing costs have shot up and the value of the pound has plummeted - wiping £3billion off markets - after Rachel Reeves shed tears in parliament on Wednesday.
The chancellor is now facing questions over her position after she repeatedly wept as she sat at Sir Keir Starmer's side during PMQs.
The scenes spooked markets and, The Telegraph reports, triggered a £3billion market sell-off, leaving the pound down almost 1% against the dollar at the end of the day.
The Times reports she told speaker Sir Lindsay Hoyle, during an altercation in the Commons, that she was "under so much pressure".
A government spokesperson, however, said Reeves was "going nowhere", and that her tears had "nothing to do with politics".
And Starmer later told the BBC she was "doing an excellent job" and would remain chancellor for "many years".
He said: "She's done an excellent job as chancellor and we have delivered inward investment to this country in record numbers.
"She and I work together, we think together.
"In the past there have been examples - I won't give any specifics - of chancellors and prime ministers who weren't in lockstep. We're in lockstep."
The prime minister said Reeves' tears were "nothing to do with what's happened this week", adding: "It was a personal matter for her, I'm not going to intrude on her privacy by talking to you."
Downing Street also denied claims that Starmer and Reeves how rowed before PMQs about the government's U-turn on welfare reforms which has left a gaping £5billion hole in Reeves' financial plans.
