Prime Minister Liz Truss defended the measures on Sunday, but said she could have "done a better job laying the ground" for the announcements.
Truss took office less than a month ago, promising to radically reshape Britain's economy to end years of sluggish growth. But the government's September 23 announcement of a stimulus package that includes £45 billion ($90 billion) in tax cuts, to be paid for by government borrowing, sent the pound tumbling to a record low against the dollar.
The Bank of England was forced to intervene to prop up the bond market, and fears that the bank will soon hike interest rates caused mortgage lenders to withdraw their cheapest deals, causing turmoil for homebuyers.
