Marks & Spencer is planning to close six stores following a review of its store estate, a move that will impact 380 staff.
The retail giant said the proposal, part of a five-year programme, is aimed at better meeting the "changing needs of customers".
M&S said it is consulting with affected staff and those impacted by the closures will be guaranteed redeployment in near-by outlets.
The stores earmarked for closure are in Worksop, Monks Cross (near York), Portsmouth, Slough, Warrington and Wokingham.
Chief executive Steve Rowe said:
Alongside the announcement, the retailer said it would open 36 new stores over the next six months as part of previously announced plans, a move that will create over 1,400 jobs.
The new outlets include 34 food-only chains, and Mr Rowe added:
Last year M&S announced it would open 200 new food-only stores and sell clothing and homewares from 60 fewer locations following years of stagnation at its general merchandise division.
