Liz Truss was pressed to justify her economic plan during an intense interview with BBC presenter Laura Kuenssberg in Birmingham on Sunday.
The cost of government borrowing has increased as a “direct effect” of Number 10’s economic measures, according to a graph that Kuenssberg pointed out.
“That is a jump in the cost of borrowing for the government which passes through to everyone else as a direct result of the measures that you announced on September 23,” she said to the prime minister.
“This is not about what was going on in the war in Ukraine already. We know that that’s a huge challenge.
“But look at the direct result on that day and the chief economist at the Bank of England…”
Ms Truss interrupted: “That is not the same as interest rates, though Laura, I think the audience should be clear that that’s not the same as interest rates which are rightly set by the independent Bank of England.
“But it is about the cost of government borrowing and that feeds through to so many other things,” replied Ms Kuenssberg.
