The government's own official and well-spun inflation figure is hitting 4.4%, craftily masking the true rise. Things must be really getting bad for the economy.
The UK's annual rate of inflation rose to 4.4% in July, up from 3.8% in June, as measured by the government's consumer price index (CPI).
The CPI is a neat little device used to set inflation at whatever the government wants it to be - usually around 3%.
It works by taking anything that's a huge inflation buster out of the equation - and then, a cunning weighting is dropped in to make those final tweaks and adjustments.
CPI inflation figures are kept artificially low by the government, because they fix public-sector pay rises, regardless of the obvious huge hike in food and fuel bills.
Inflation used to be measured by the retail price index (RPI) - but New Labour ditched that in 2003.
The CPI may be a less effective measure of price rises than the old RPI, but it's much easier to manipulate. A point made repeatedly by the Conservatives.
The jump in inflation from 3.8% to 4.4% was the biggest monthly change in the annual CPI rate since records began in 1997.
More holiday reading for beleaguered Brown and his doomed chancellor, Alistair Darling.
