Inflation falls on both measures
Inflation fell on both main measures in March. The annual rate of inflation — as measured by the Retail Prices Index (RPI) — was down to 2.5% from 2.7%.
Under the Consumer Prices Index (CPI) — the measure generally used by the coalition government — inflation was once again below the Bank of England’s 2.0% target and fell to 1.6% from 1.7%.
