Alongside relocations, conversions, downsizes and the introduction of concessions, these closures will radically reshape M&S's Clothing & Home space.
"Closing stores isn't easy but it is vital for the future of M&S".
M&S closures are imminent as the retail giant undergoes a huge shake up - and hundreds of people will lose their jobs.
Last year, M&S said United Kingdom and worldwide closures and impairments resulted in £190m of charges, which were partly responsible for the retailer's decline in annual profits.

GlobalData has forecast that its clothing market share will be 7.6% this year - nearly halving in two decades - despite opening more stores selling clothing, homewares and food under the one roof.
