It will be perceived as conjuring up money by voters who believe the household budget analogy whose use you continue to defend.

That’s in the hands of Labour comms, but since you are the only person I’ve spoken to that has come to that conclusion, I fear you’re not as representative as you think you are.

Incidentally whatever the markets consider the govt has in headroom for borrowing won't be changed by changing the definition of debt. Market makers aren't stupid. They know the household budget analogy is bonkers.
