Waitrose has revealed that it will be opening two additional "market town" style shops as it tests its new format of smaller-scale stores.

Last week, the UK retailer revealed its first "market town" store will open this month in St Neots, Cambridgeshire.

The additional stores will open in Buckingham and Brackley, Northamptonshire, in June and July.

"Through the new format we hope to create the atmosphere of a traditional grocery shop," a spokesperson for the company said. "We will achieve this by selling locally-sourced fresh produce in smaller stores."

Currently, the majority of Waitrose outlets have 20,000-25,000 square foot of selling space. The new format will see Waitrose operating stores that have 10,000-15,000 square foot of selling space.

"Our brand has traditionally had a 'sweet spot' of around 20,000 square foot, but in a competitive environment we need to be more flexible and improve the potential of the smaller shops in our estate," Waitrose managing director Mark Price said. "The market town format will allow us to achieve that, as well as giving us new opportunities to grow the business."

Each market town store will reflect the needs of the local community - the store design and range carried will vary from location to location and a "community wall" will feature local information.

Over half the store will be devoted to fresh products and the amount sourced locally will increase by 200%, the company said.
