Competition between suppliers will help ensure price rises are minimised, a senior minister has told RN.

Andrea Leadsom, secretary of state for the Department of the Environment, Farming and Rural Affairs, said: “Food prices are very competitive in this country and we’ve seen food price deflation in recent years. They do move up and down, but the competition between a broad range of products on offer will ensure we will remain competitive.”

Walkers’ smart potatoes use 50% less carbon and water than previously

Ms Leadsom was speaking at an event organised by PepsiCo this week to celebrate its ‘5 in 50’ initiative which has reduced the carbon and water used in producing Walkers crisps.

The company has also reduced its delivery mileage by four million miles annually through efficiencies.

UK general manager Ian Ellington said he was “open to ideas” on how PepsiCo could support independent retailers to make environmentally-friendly changes to their own operations.
