The company, formed 18 months ago from the merger of Orange and T-Mobile, said the cuts would affect employees at its sites in London, Bristol, Hatfield and Darlington, who were briefed on Wednesday about the changes.

Everything Everywhere said the changes reflected “a new phase focused on accelerating the delivery of its ambitions” and that it “recognised and would like to thank” the affected employees, who will be placed in a three-month consultation period.
