Marks and Spencer retail director Guy Farrant has initiated a divisional restructuring at the store group, designed to improve efficiency and effectiveness in how the stores are run.

In one of the most significant changes made since Farrant took up his post in April, the business will be run on a geographical basis rather than by store format type – such as Simply Food or high street – as was the case in the past.

An M&S spokeswoman confirmed a new five-region structure, but declined to disclose details of any associated personnel or other changes. However, she said that there had been no redundancies.

The high street giant posts interim results on November 6, when chief executive Stuart Rose may elaborate on the improvements the new approach is expected to deliver.

Shortly after taking up the post, Farrant said his priority was to ensure shops live up to the retailer’s promise of providing better product, service and environment.

As multichannel grows to account for a bigger proportion of M&S’s business, he is especially determined to ensure that standards are maintained and improved as new services, such as in-store collection of goods ordered online, are introduced.
