Derek Weir is to step down as vice-chairman of Motherwell and will leave his position as a Scottish Premier League board member.
Weir, who has recently represented the club at SPL meetings over the Rangers crisis, will remain on the Fir Park board.
"The club has been advised by Derek Weir that he will be stepping down from the role of vice-chairman," a club statement read.
"Over the past two years Derek has dedicated a significant amount of his personal time to working on club issues and representing the club on the SPL board.
"As a result of the number of extremely difficult and complex issues currently facing the game, Derek feels he is no longer able to make the time commitment required to properly fulfil the role at the club and that he needs to refocus on his other business and family matters.
"He has also advised the executive of the SPL that he will not be seeking re-election to the board at the AGM on July 16.
"Derek has agreed to remain a director of Motherwell FC and will continue to assist the chief executive and other board members in what is an extremely difficult period for the club.
"We would like to thank Derek for the significant contribution he has made to the club in his role as vice-chairman during the past two years."
The news came ahead of an anticipated result of the ballot of Well Society members over the Rangers newco application to the SPL.
