Dixons Carphone has narrowed its profit forecasts after the company detailed weak Christmas trading at its UK and Ireland division as it continues to come up against more cautious consumer spending.

But the company's chief executive, Seb James - who is leaving to run chemist chain Boots - noted a "strong sales period" for the UK mobile business thanks in part to better availability of the iPhone X, but said current market conditions meant that "gross margins continue to be challenged in phone".

Mr James will be replaced in April by Shop Direct chief executive Alex Baldock.

The company reported a six per cent rise in like-for-like group revenues for the 10 weeks to January 6, propped up by double digit like-for-like growth in its Nordic and Greek division, up 11 per cent and 23 per cent, respectively.

It struggled from a weaker rise in sales in its UK and Ireland division where like-for-like revenues rose just three per cent.

Chief executive Seb James - who the company revealed late on Friday was leaving to work for Boots - said he was "satisfied" with the regional performance given the "more cautious consumer environment".

Dixons Carphone went on to lower the top end of its pre-tax profit forecasts on Monday to a range of £365m and £385m, from previous estimates of between £360m and £400m.
