Fifa's independent ethics investigator Michael Garcia has quit in protest over the handling of his report into bidding for the 2018 and 2022 World Cups.
The American lawyer cited a "lack of leadership" at the top of football's world governing body.
Garcia said he lost confidence in the independence of judge Hans-Joachim Eckert, an ethics committee colleague.
Uefa president Michel Platini said: "We wanted all transparency but this is a new failure for Fifa."
The head of European football spoke out as Garcia resigned a day after Fifa's appeals panel rejected his challenge of Eckert's summary of his report.
Garcia said: "It is the lack of leadership on these issues within Fifa that leads me to conclude that my role in this process is at an end."
Russia won the right to host the 2018 World Cup, while Qatar was awarded the 2022 tournament. Fifa cleared both of corruption despite a series of allegations
Garcia's findings were released as a 42-page summary of the 430-page report.
He said the summary was "erroneous" and complained to Fifa, which said his appeal was "not admissible".
In his resignation statement, he said: "No independent governance committee, investigator, or arbitration panel can change the culture of an organisation."
Garcia said his submission to the Fifa appeal committee outlined what he called "the most serious failings" of Eckert's response.
"Among other points, the brief explained why, when viewed in the context of the report it purported to summarise, no principled approach could justify the Eckert Decision's edits, omissions, and additions," he said.
Fifa meets in Morocco this week and will decide whether to release a full, redacted copy of Garcia's report.
