Slowing food prices in the United Kingdom helped drive a surprise fall in inflation in August, with the cost of living now at its lowest level in a year and a-half.

Official figures show inflation, which measures how prices change over time, fell to 6.7% in the year to August, down from 6.8% in July.

It is the third month in a row that the figure has dropped.

Price rises for milk, cheese, and eggs slowed the most, while fish and vegetable prices also eased.

There was also a drop in hotel and air fare costs, although fuel prices jumped.

When the rate of inflation falls, it does not mean prices are coming down, but that they are rising less quickly.
