Tom Alexander, the chief executive of Everything Everywhere, has resigned his position after a year in post.
Alexander, who joined Orange in 2008, will step down on 31 August, Everything Everywhere said in a statement on Monday. The company said Alexander is leaving for personal reasons, and will be replaced by Olaf Swantee, France Telecom's executive vice president of operations and sourcing in Europe (except France).
"There is never an easy time to leave a company that you care deeply for but, for personal reasons, I feel now is a good moment to step back," said Alexander in a statement. "I am delighted to welcome Olaf into his new role."
Some analysts have described Everything Everywhere's financial performance as "disappointing". Alexander has resigned to spend more time with his family, and his leaving has "nothing to do with the results", an Everything Everywhere spokesman told ZDNet UK on Monday.
Alexander became chief executive of Everything Everywhere when Orange UK and T-Mobile UK merged on 1 July 2010. Swantee will take up the chief executive position on 1 September 2011.
