Millar, 53, is leaving in December “to pursue other career activities”, a statement from Ryanair said yesterday. However he is not cutting all ties, as he will become a non-executive director.
He follows in the footsteps of former deputy chief executive Michael Cawley, who left Ryanair earlier this year after 17 years. Chief executive Michael O’Leary has said he has no plans to leave.
Millar’s deputy, finance director Neil Sorahan, is set to take over as CFO at the end of the year.
It was a day of high drama for the airline yesterday, as two of its jets collided at Stansted Airport.
At around 6.45am the wing-tip of one Boeing 737-800 clipped the tail-cone of another. No one was injured and the Air Accident Investigation Board is investigating.
