EE CEO Olaf Swantee will step down after the completion of BT’s £12.5bn takeover of the mobile network operator.
The deal, which is in the last stages of regulatory approval, is expected to close next month. It will combine the UK’s largest mobile operator with the largest player in fixed broadband and fixed voice networks.
Swantee joined EE from French telecommunications firm Orange. He led the integration of Orange UK and T-Mobile, which merged to establish EE in 2010.
Swantee will be replaced by EE’s chief commercial officer Marc Allera, who has been at the company for four years.
Commenting on his departure Swantee said: "As we approach the imminent completion of the deal with BT and the start of an exciting new chapter for EE, I’ve taken the enormously difficult decision to step down from my role as CEO, and pursue new opportunities.
"I am immensely proud of the past four and a half years, creating, launching and growing EE to the exciting business it is today."
