UEFA has reportedly warned FIFA president Gianni Infantino that it could seek a no-confidence vote unless he resigns.
The reported confrontation followed the withdrawal of a proposal to sell 30% of World Cup commercial rights to private investors for £15 billion.
UEFA was said to have stated that its 55 member associations were ready to participate in such a vote.
It was also said to cite FIFA statutes under which 43 supporting national associations would be enough to remove a president.
UEFA accused Infantino of acting without sufficient transparency and accountability, allegations that have not been independently corroborated within this evidence set.
The organisation also alleged that FIFA held $5 billion in bank reserves while the commercial-rights proposal was being considered.
CONCACAF and the English Football Association were said to have backed the proposed no-confidence action.
CONCACAF was quoted as describing the matter as a failure of leadership and governance.
The Qatar Football Association, by contrast, was said to welcome the withdrawal of the proposal and to support Infantino’s efforts to expand football globally.
Claims of internal opposition among FIFA employees were also made, but the evidence does not establish the scale, organisation or official status of any such activity.
No direct response from Infantino or FIFA, nor confirmation that a formal vote has been scheduled, is contained in the supplied evidence.
