UK CPI inflation fell for a sixth consecutive month in March to hit a fresh four-year low, according to latest figures from the Office for National Statistics.
CPI inflation fell from 1.7% in February to 1.6% this month, the ONS said, in line with economists' expectations and continuing the trend seen in recent months.
The figure is the lowest level seen since October 2009, when CPI inflation stood at 1.5%.
The largest contribution to this month's fall came from transport, particularly motor fuels, according to the ONS.
CPI inflation has now fallen every month since September 2013, when the rate stood at 2.7%.
The ONS added that CPIH - the measure of inflation which includes housing costs - fell from 1.6% to 1.5% on the month.
Capital Economics' UK economist Samuel Tombs said there is little sign of increasing price pressures in the coming months.
"Today's producer prices figures, showing that factory gate inflation eased from 0.6% to 0.5% in March, suggest that price pressures in the inflation pipeline are still extremely weak," he said.
