In an interview with the Observer, the whistleblower claimed that Vote Leave had donated some 625,000 pounds ($881,540) to the founder of a different group, BeLeave, Darren Grimes, before the June referendum. Furthermore, Sanni alleged that the funds went to Canadian data firm Aggregate IQ, which has been linked to Cambridge Analytica, the leading data mining firm that used Facebook data to develop a mechanism that would allow it to predict and influence voter behavior.
While Vote Leave chief Dominic Cummings, as well as Grimes, has denied the allegations, saying that he had checked it with the Electoral Commission before donating money to the group, Sanni has insisted that the official Brexit campaign violated referendum rules.
Sanni claimed that everything passed through Vote Leave manager Stephen Parkinson, who turned out be the whistleblower’s ex-boyfriend.
"I know that Vote Leave cheated… I know that, that people have been lied to and that the referendum wasn't legitimate. Leaving the European Union, I agree with. But I don't agree with losing what it means to be British in that process; losing what it means to follow the rules; losing what it means to be quite literally a functioning democracy," Sanni told Channel 4 News.

Parkinson issued a “personal statement” to Channel 4 News, where he denied the allegation, saying that he was “saddened” by the “factually incorrect and misleading” claims from Sunni, who previously blamed Parkinson for outing him as gay and forcing to tell his family in Pakistan the truth about his sexual orientation, which could put them in danger.

Sanni said that he had reported the overspending allegation to the Electoral Commission on March 22.
"In effect they used BeLeave to overspend, and not just by a small amount… Almost two thirds of a million pounds makes all the difference and it wasn't legal. They say that it wasn't coordinated, but it was. And so the idea that the campaign was legitimate is false," he added.
The Electoral Commission has refused to comment on “live investigations,” having only mentioned that it had a “number of investigations open in relations to campaigners at the EU referendum.”
