David Baldwin is to stand down as chief executive of the EFL, having only taken on the role in June.
A statement from the league confirmed the former Burnley CEO would leave in six months' time. The league said the decision was totally unrelated to Project Big Picture, the plans for reforming the English football pyramid which involve EFL chairman Rick Parry.
David Baldwin said: 'Having thoroughly reflected on my own personal circumstances at length in recent weeks, I have now determined it is only appropriate to inform the board and the membership of the EFL of my intentions at the earliest opportunity.
