Monsoon took on debt for the first time in its 30-year history after investing£75.5 million in the business.
Over the course of the year, 61 stores opened in the UK and the Republic of Ireland, and 117 outlets internationally. The group said that because of tough trading conditions, integrating the 43 stores acquired from Etam had proved more complex that originally thought.
