Parkes, who has been director of comms for two-and-a-half years and does not have a job to go to, said: ‘Following the acquisition, I have made a personal decision to leave, take a bit of time out and follow other opportunities.’
It is not clear whether Parkes’ role will be filled, but it is understood that the eight-strong comms team will report to Tim Hawkins, Stansted's regulation and planning director.
MAG added Stansted to its portfolio of Manchester, East Midlands and Bournemouth airports in February.
It is not known if the merger will impact on the PR team.
Before his time at Stansted, Parkes spent four years at United Utilities as head of government relations. He also worked in the comms team at Transport for London and for BBC’s Question Time as a broadcast journalist.
Parkes added: ‘I have enjoyed a wide spread of comms disciplines and am keen to pursue a new role as a comms director or similar in an interesting sector.’
