**Interviewer:** Recent reports indicate that UK government borrowing reached £16.6 billion last month, making it the third-highest figure for September since records began in 1993. Can you elaborate on what this means for the Treasury and its upcoming Budget?

**Darren Jones (Chief Treasury Secretary):** Absolutely. This figure underscores the fiscal challenges we’re facing. The new Labour government has inherited what I would describe as a fiscal “black hole.” Addressing this will necessitate some tough decisions moving forward.

**Interviewer:** With such high borrowing figures, what can we expect in terms of fiscal policy during the Budget on October 30th? Will there be changes to tax or spending?

**Darren Jones:** It’s certainly a pivotal moment. Economists are speculating that our government may need to consider raising taxes or cutting spending as part of our strategy to manage long-standing debts. We are also contemplating adjustments to our self-imposed debt rules, which could provide us with more flexibility to invest in key infrastructure projects.

**Interviewer:** How are economists interpreting these recent numbers?

**Cara Pacitti (Senior Economist, Resolution Foundation):** The data clearly illustrates the significant challenges the Chancellor faces when planning the upcoming Budget. Spending increases have stemmed from higher debt interest and public sector pay raises, including the increases implemented for junior doctors to resolve last July’s strikes.

**Interviewer:** Interestingly, while the overall expenditure has risen, the social benefits bill has actually decreased. Could you explain that?

**Cara Pacitti:** Yes, that’s correct. The reduction to the winter fuel payments for wealthier pensioners has more than offset the annual increase in inflation-linked benefits, leading to a decrease in the overall social benefits expenditure.

**Interviewer:** Would you say that the Chancellor has some room for maneuvering despite these setbacks?

**Alex Kerr (UK Economist, Capital Economics):** While it’s too late for these September figures to alter the Budget forecast, they do highlight the limited space the Chancellor has to increase day-to-day spending without raising taxes. However, if she decides to adjust the fiscal rules, there could still be an opportunity for increased public investment.

**Interviewer:** What does this increased borrowing mean for the UK’s national debt in relation to its economic output?

**Alex Kerr:** As of the end of September, the UK’s national debt stood at 98.5% of its economic output. While this reflects a slight decrease from the previous month, the levels are still comparable to what we observed in the early 1960s, which is significant.

**Interviewer:** Thank you for your insights. This will surely be a critical period for the UK economy as the government navigates these challenges.
