They prepared him one setting out the course we were on when he started. Not published.
They supplied a draft on the 6th, how close that is to complete is a different matter (I’d agree it could well have been a finished draft, but that’s not known?)
I can’t find the quote now, but in the last treasury select committee meeting with the OBR the wording was allong the lines of ‘this normally takes 10 weeks, we were commissioned at the end of July (so about 6 weeks to the 6th Sept) and will try to produce something that meets our minimum standards/obligations’.
Although we’re now ~10 weeks so maybe that’s why they’re meeting again.
