After the departure of previous IT director John Sacher as part of Marks & Spencer's cost-cutting programme last year, Keith Bogg took on the role of divisional director of IT and distribution.
Last year, Bogg was involved in the group's electronic point of sale (epos) and warehouse software/ hardware upgrades. It is believed Bogg recently asked for a new assignment and was happy to move sideways. Bogg is now heading M&S's e-commerce drive and also managing the company's direct phone catalogue business.
Head of e-commerce Peter Robinson, who has pledged to increase the on-line range of M&S products to 3,000 from the current limited range, will answer to Bogg.
An M&S spokesman said, "We are looking for an IT director who will primarily be responsible for pure IT and business systems, who will be more inward-looking, by looking after the running of the company.
"We are making sure we get the right person, rather than making a rash appointment, so there is no timescale for the appointment."
Until a replacement is found, board director Guy McCracken will be responsible for corporate IT.
