Dixons Carphone deputy chief executive Andrew Harrison has stepped down from his role and the group’s board to become chairman of its Carphone Warehouse business. 

Harrison – a Carphone Warehouse lifer – will take up his new post with immediate effect.

In a statement, he said he wanted to focus his attention “more sharply” on the mobile phone business, which is currently struggling amid a slowdown in the UK postpay mobile phone market. 

Group chief executive Sebastian James said: “We are aware that this part of our business, while retaining a high degree of appeal and relevance to customers, operates in a market where customer behaviour is changing.

“As we reposition our model to enable Carphone Warehouse to flourish in this changing world, there is nobody better qualified or more able to lead this transition than Andrew.”

Harrison added: “I am extremely proud of what we have achieved through the merger of Dixons Carphone over the last three years.

“With the ongoing changes in the mobile market, I now want to focus my attention more sharply on Carphone Warehouse, a business that has been close to my heart for over 20 years, as we enter the next stage of its development.”

The directorate change comes a week after the electricals giant reported plummeting interim profits, and unveiled plans to restructure its mobile phone business. 

James remained tight-lipped on the specifics of the plan but said the firm was in the early stages of discussions with network providers.
