LONDON (Reuters) -British shop prices rose this month by the most since March last year, potentially adding to the Bank of England's worries about how long the country's high inflation problem is likely to last.

he British Retail Consortium (BRC)-NIQ Shop Price Monitor reveals food inflation hit 4.2% this month, up from 4% in July, marking the highest level since February 2024. Bosses at the trade body warned the acceleration "adds pressure" to families already struggling with the cost of living.

The rising cost of chocolate, butter and eggs has helped drive food price inflation to its highest in 18 months, a survey says. Food inflation hit 4.2% this month, compared with 4% in July, according to the British Retail Consortium latest shop price monitor. It is higher than at any time since March of last year, when it was 3.7%.
