On a monthly basis, prices fell 0.9%.
Core inflation, which strips out volatile food and energy prices, clocked 7.0% year-on-year, also slowing from a reading of 7.3% in December.

the fastest pace of consumer price rises since 1992, stoked by
soaring energy and food prices after Russia's invasion of
Ukraine.
