Fashion retailer Karen Millen has reported widening losses and falling sales for its last full year.

Operating losses widened to £10.5m, from £9.7m, in the year to February 27, 2016.

Karen Millen attributed this to digital infrastructure investments and a weaker performance in key markets such as Russia.

Total sales fell 10% to £161m. A like-for-like sales figure was not disclosed. 

In the UK, the picture was slightly more positive with sales remaining flat against a “challenging” backdrop for fashion retailers. 

The retailer has spent a year without a permanent chief executive following the departure of Mike Shearwood in September last year.

Former Bonmarché boss Beth Butterwick took over the top job in August.

Butterwick said: “The results for the year to February are in line with expectations given the retail environment and much-needed, significant investment in the business.

“We are encouraged by the early impact of our investment in digital and are focused on putting the right building blocks and strategy in place to grow Karen Millen and develop a truly omnichannel business.

“I am looking forward to leading our new, strong management team as we develop and grow the business.”
