Jacamo and Simply Be owner N Brown has issued a profit warning after warm weather this autumn hurt sales of winter clothing.

The group said that it now expects full-year profits of between £88 million and £92 million, compared to the £103 million originally forecast.

Angela Spindler, chief executive, said: "We have stepped up the pace of change in the business designed to unlock the potential value we see in a proposition built around fashion that fits. In modernising the way we operate and the way we go to market, we are focused on: attracting more customers by raising brand awareness and broadening our appeal; building customer loyalty through further product and service improvements; and creating a modern scalable infrastructure so that the business is fit for the future. Despite the negative effects of recent market conditions on performance, I am confident that we are taking the right actions and are making good progress."
