Brexit architect Nigel Farage on Thursday predicted a possible rerun of the 2016 ballot in the near future, warning if that happens, "it's no more Mr. Nice Guy."

At a Leave Means Leave rally in London, the former U.K. Independence Party leader urged the crowd to "face reality" as Britain's last-minute scramble to shape an exit from the European Union stalls, U.K.'s The Independent reported.

"Let us prepare, let us organize," he told the crowd, the Express reported. "If I have to fight again against this lot, then believe me, next time, as far as I'm concerned, it's no more Mr. Nice Guy."

"I don't want it anymore than you do," he added, The Independent reported. "But I am saying to you, we have to face reality in the face. Don't think the other side aren't organized, don't think the other side aren't prepared, don't think they haven't raised the money, don't think they haven't got the teams in place. They have."
