LONDON, Dec 10 Reuters British shoppers faced increased pressure on their budgets last month after grocery price inflation edged higher, industry data showed on Tuesday.

Market researcher Kantar said annual grocery price inflation was 2.6 in the four weeks to Dec. 1, having been 2.3 in the previous fourweek period.

Prices are rising fastest in products such as toothbrushes, chilled smoothies juices, and fragrances and falling fastest in items including household paper products, dog food and ambient savoury meals, Kantar said.

Among individual supermarkets, Britain39;s biggest, Tesco, saw sales in the 12 weeks to Dec. 1 rise 5.2. It had a market share of 28.1, its highest since December 2017.

UK supermarkets have warned that tax rises in the new Labour government39;s first budget in October, together with another rise in the national minimum wage, will be inflationary.

Official data published last month showed overall UK inflation jumped to 2.3 in October. Data for November will be published Dec. 18.
