Laporta also thanked the supporters who participated in the vote.
"I want to make special mention of the members who came out to vote. It has been a celebration of democracy and civic spirit."

He added that he would continue to support the club despite the setback.
"Barca is the club of my life. I will continue to work and fight so that Barca becomes the club I dream of."
