The fall in the Consumer Prices Index (CPI) measure of inflation to 1.5% marks the lowest in four-and-a-half years.
Falls in the cost of transport services, particularly air fares, were the largest contributor to the fall, the Office for National Statistics has said.

CPI equalled the rate seen in October 2009. It was last lower, at 1.1%, in September 2009.

Labour said the Government is "complacent about the cost-of-living" crisis after inflation rose to 1.8% today which stalled hopes for a pick-up in real terms wages.
These figures underline why this Tory-led government is wrong to be so complacent about the cost-of-living crisis.
Wages after inflation have fallen by an average of £1,600 a year since 2010 and the link between the wealth of the nation and family finances is broken. A huge turnaround is needed to ensure working people aren’t worse off than when David Cameron came to office.
While the Tories try to deny it even exists, Labour has a clear plan to deal with the cost-of-living crisis and earn our way to higher living standards for all, not just a few at the top.
