The chief executive of homewares retailer Dunelm is to step down with immediate effect for "personal reasons".
Dunelm said John Browett, who was appointed as boss in 2015, had made "good progress over the last two years", but added that the next "phase of growth requires different leadership".
Chairman Andy Harrison will step into the breach on an interim basis, supported by deputy chairman Will Adderley and finance chief Keith Down.
Mr Browett said: "I am pleased to have led the development of Dunelm over the last few years and feel that we have achieved much in a challenging retail environment.
"It is, however, time to move on to a new challenge, and I am looking forward to the next chapter of my career."
The news comes after Dunelm warned in February that costs were starting to rise in the face of the Brexit-induced collapse in the value of the pound, resulting in a more "challenging" retail environment.
Mr Harrison said: "I would like to thank John for his contribution to the business and the strategic progress made under his leadership, most notably the exciting acquisition of Worldstores."
