LONDON, Dec 6 (Reuters) - British grocery inflation edged lower in November, a first decline in nearly two years, but remained near record highs, providing little relief for consumers ahead of the key Christmas trading period, industry data showed on Tuesday.
Market researcher Kantar said grocery inflation in the four weeks to Nov. 27 was 14.6%, down 0.1 percentage points from October's record high, marking the first fall in 21 months.
Prices are rising fastest in markets such as milk, dog food and butter, said Kantar.
It said grocery sales rose 5.9% year-on-year in the 12 weeks to Nov. 27, masking a drop in volumes once inflation is accounted for.
Kantar said its data did not indicate a significant boost to sales from the soccer World Cup, which started Nov. 20.
