Deflationary pressure continued for the sixth month in a row with inflation dropping to a new low of (-)2.65 per cent in April, mainly on account of decline in prices of fuel and manufactured items even as food prices increased.
Inflation, as measured on the Wholesale Price Index, has been in the negative zone since November, 2014.
In April last year, it was 5.55 per cent.
