Thank you for that question.
The government has for a number of years been moving its balance of public debt to a 60% fixed-rate debt, a longer-term debt at a set rate, and then a 40% floating-rate debt. The increase in the public debt charges is a result of the increase in the average interest rate on all the debt, but effectively on the floating-rate debt, and I'll get the precise figure for you in a second. The difference is the treasury bill rate for the last mains was 3.4%, i.e. the short-term debt rate, which is the relevant rate, and it's increased to 4.1%, the projected rate now. That explains the difference between the two.
