Joan Laporta has called on his fellow Barcelona presidential candidates to unite against election favourite Josep Maria Bartomeu.
Laporta, who previously served as president between 2003 and 2010, is the primary rival for Bartomeu at the upcoming election, which takes place on July 18.
Bartomeu, who has stepped down ahead of his bid for re-election, appears to be the frontrunner after strengthening Barca's financial position as well as overseeing success in La Liga, the Copa del Rey and the Champions League last season.
Laporta, making an appearance on "El Punt Avui," has now called on fellow candidates Agusti Benedito and Toni Freixa to join together in a bid to ensure Bartomeu does not return to the helm.
"I think those that are here -- all the candidates, with the exception of Josep Maria Bartomeu -- could go together," he said, according to Sport. "If we do not want Snr Bartomeu to be president, we have to join forces."
In an appearance on "Els Matins," reported by AS, Laporta added: "The polls show that the intention to vote for Benedito and Freixa is low. It's impossible that they will win. If I was them, I'd channel support to either the Bartomeu/Rosell campaign or my own."
Sandro Rosell had been Barca president until January 2014, when he resigned amid controversy over the Neymar transfer, and was replaced by Bartomeu, who had been his vice-president.
Laporta has been keen to paint that regime in a negative light.
He has previously said he would end Barca's controversial sponsorship deal with Qatar Airways as well as attacking the decision to sign Arda Turan before the election and drawing attention to the Neymar deal.
He also used his "Els Matins" to draw attention to the doubts over Lionel Messi's future at the start of the year, saying: "Last season there was talk of selling Leo. With me he will feel far more comfortable."
Bartomeu, meanwhile, said at an electoral event in Sitges that he would prefer that his rivals stood individually.
"I think that it is good for Barca that there is a higher number of proposals, of options," he said. "That would be better."
