Mobile phone retailer Phones 4u has today announced of three key management roles changes, after reporting positive results for its last financial quarter.

Total sales increased 10.4 per cent across the 586 store group in the final three months of 2011, although no like-for-like (LFL) trading figures have been made public, while contract growth grew 4.3 per cent across its retail division LFL.

In response to this performance the retailer‘s current CEO for Distribution Phil Dobson has been promoted to Deputy Group CEO, and Mary Grant and Chris Harris have joined the business as Distribution CEO and Lifestyle Services Group CEO respectively.

Grant leaves her position as Managing Director of Bus & Rail division at transport operator FirstGroup, while Harrison‘s previous position was as CEO of Combined Insurance in Europe for global commercial property and casualty insurance organisation Ace Group.

Tim Whiting, Group CEO for Phones 4u, commented: “I believe this is the right time to invest further in the business and I am delighted to announce the promotion of Phil Dobson to Deputy Group CEO following his successful running of both divisions within the group.

“In addition, I am pleased to welcome Mary Grant and Chris Harrison to the group, both of whom bring with them proven track records of strong leadership and of delivering financial growth.

“Alongside this, I am very happy with the performance of the business during the last quarter of 2011. We continue to gain market share thanks to our focus on giving our customers excellent service and value and there is no doubt that investment in our stores, systems, and people have been reflected in our performance for the period.

“Despite the tough conditions we are seeing on the high street, I‘m confident that we can maintain this positive momentum into 2012.”

Phones 4u earned the unenviable title of most complained about advert of 2011 late last year, according to the Advertising Standards Authority, in response to its TV promotion which featured a dead child haunting a woman in a car.
