Sharecast - At 0850 BST, the FTSE 100 was down 0.3% at 7,889.37.
Figures released earlier by the Office for National Statistics showed that consumer price inflation was 10.1% in the year to March, down from February’s surprise 10.4%. Economists were expecting a fall to 9.8%.
On a monthly basis, CPI rose by 0.8%, compared to a rise of 1.1% in March.
The largest downward contributions came from motor fuels and heating oil prices, but soaring food prices weighed heavily. Food inflation hit a fresh 45-year high of 19.2% in March, from February’s 18.2%.
Once more volatile energy, food, alcohol and tobacco prices were stripped out, core CPI including owner occupiers’ housing costs (CPIH) rose by 5.7% in the 12 months to March, unchanged on February. Core CPI was 6.2%, above forecasts for 6.0%.
Capital Economics said: "Plunging energy price inflation will soon drag down CPI inflation more significantly, but the stubbornness of core inflation suggests that the fight against inflation is lasting longer than the Bank of England expected.
"This supports our long-held view that the Bank will raise interest rates to 4.50% (from 4.25% now) in May. It’s possible that rates may have to rise higher."
