Barcelona president Josep Maria Bartomeu announced on Tuesday his resignation from his post following increasing fan pressure and a public fall-out with Lionel Messi.
Bartomeu, who became president in 2014, was set to receive a vote of no confidence as fans tried to sack him.
He fell out with forward Messi after the Argentina striker handed in a transfer request in August.
His resignation, which includes the entire board of directors, follows Saturday's 3-1 defeat to Real Madrid.
