Dixons Carphone headline pre-tax profits have slumped 22 per cent to £298 million.

The firm also said revenue was down 1% to £10.43 billion in the 12 months to April 27.

Dixons Carphone said headline profits would slide again in the 2020 financial year to £210m.

Chief executive Alex Baldock said: "In UK mobile, the market is changing in the way we described in December, but doing so faster.



"So, we're moving faster to respond: we've renegotiated all our legacy network contracts, we're developing our new customer offer and are accelerating the integration of mobile and electricals into one business.

"This means taking more pain in the coming year, when mobile will make a significant loss."

Fashion retailer N Brown has posted further sales declines, but insisted its turnaround strategy is bearing fruit as online trade lifted.

The group said total revenue dropped 3.8% in the 13 weeks to June 1, dragged lower by a 5.4% fall in product sales from the managed decline of its traditional, mail order business.

Its shift away from catalogue business saw online sales rise 3% in its first quarter, with 83% of total revenue now digital.

Steve Johnson, chief executive of N Brown, said: "We're pleased to report a solid trading performance in the first quarter.

"In line with our strategy, we delivered digital revenue growth across JD Williams, Simply Be, Ambrose Wilson and Jacamo as we continue to improve our customer offer whilst managing the decline of our legacy offline business.

"The retail market remains challenging, but we have a clear strategy to deliver profitable digital growth and our full-year expectations are unchanged."
