Britain's inflation rate dropped from 3.5 percent in March to 3 percent in April, the Office for National Statistics (ONS) announced on Tuesday.

The Consumer Price Index (CPI), a major gauge for inflation, fell to 3 percent in April, the lowest level since February 2010. Meanwhile, the Retail Prices Index measure fell to 3.5 percent from 3.6 percent in March.

ONS said transport, alcohol and clothing were the most significant drivers behind the fall in inflation, which charts the cost of living in Britain by tracking prices of a basket of goods.

The largest upward pressure to the change in CPI came from the operation of personnel transport equipment, restaurants and hotels, and rents.

The Bank of England trimmed its growth forecast for Britain and warned that inflation will remain above target for another year.

According to its quarterly Inflation Report, the central bank abandoned a longstanding hope that consumer price inflation will fall back to the official 2 percent target by the end of the year.
