The most complicated set of UK public finance figures in history.
In theory, public finance statistics ought to be pretty simple: they are, after all, merely a ledger of how much the Government has raised in taxes, how much it has spent and how much it has borrowed in a given year.
However, these days we have a grand total of six (count 'em) different headline measures of the deficit.
1. There's public sector net borrowing (PSNB) - the traditional measure of the deficit. On this measure, the deficit is down this past financial year (12/13) by £19.1bn (or 20.5%) to £74.2bn.
2. Strip out the effects of financial interventions (eg the semi-nationalisation of banks like RBS and HBOS) and the deficit was £86.2bn in 2012/13 - a higher number, yes, but down by 28.7% on the previous year. This is PSNBx.
3. Strip out the impact of the Royal Mail Pension Plan, which has been added to the Government's books, and the deficit was £114.2bn - down by a rather less flattering 5.6% compared with '11/12.
4. If, on top of this, you then strip out the effect of the extra money funnelled into the public finances from the Bank of England’s Asset Purchase Facility (eg profits from quantitative easing) the deficit last year was £120.6bn, down a mere 0.3% from last year.
5. It doesn't end there, though. The Office for Budget Responsibility has also calculated a variety of the deficit which, on top of all of the above excludes the influx of profits from the Special Liquidity Scheme. On this measure, the deficit was actually £2bn higher in 2012/13 than the previous year.
6. And if you exclude the impact of the reclassification of Northern Rock Asset Management and Bradford & Bingley (but exclude the SLS impact - do keep up) the deficit was, again, higher than last year, this time by £400m.*
Now, according to Treasury sources (who have spent the morning insisting to me that today's public finance figures are "hardly very complicated"), the only figures from above to pay any attention are 2) PSNBx and 4) PSNBx excluding the Royal Mail Pension Fund and QE profits. On both of these measures, the deficit has fallen, although in the case of the underlying measure (4) it's only by a few hundred million pounds, which in the realms of public finance numbers is essentially a rounding error.
