Documents relating to Gianni Infantino’s failed World Cup sell-off will be made available to Fifa’s ruling council – but only if members agree to fly to Zurich to view them.

Amid a leaks clampdown against Infantino’s critics, the Fifa Forward Enterprise (FFE) blueprint will only be made available for viewing in person at the governing body’s headquarters.

Plans to accept a demand for access to details of the Fifa president’s collapsed scheme were partially accepted in a letter sent by Mattias Grafstrom, Fifa’s secretary general, to council members. It was sent as the deadline was reached for the governing body to respond to a series of questions about the controversy from Uefa.

Infantino had been given two weeks to provide “information or documents” by Uefa. A list of 42 questions addressed to Grafstrom covered issues that European football leaders claimed were not adequately addressed at a recent Fifa Council meeting. Topics included FFE, the Folarin Balogun red-card furore and the inaugural Fifa Peace Prize handed last year to Donald Trump.

During a three-hour council meeting last month, Infantino apologised for failing to communicate his sell-off plan, but still failed to satisfy European football leaders regarding their recent concerns.

Fifa informed its council members “they will be granted access to view key documents” concerning FFE, a source confirmed. To preserve Fifa’s confidentiality obligations, “council members have been invited to register their interest, within the next two weeks, to view documents, in person, under specific conditions, at Fifa headquarters in Zurich,” the insider added.

Uefa’s two-week deadline to respond to its questions has been viewed as “unfeasible”, however, while Fifa has been overseeing a new youth World Cup in Baku, Azerbaijan.

“The ongoing legal action in the United States has also created legal boundaries,” the insider added. “Fifa has maintained it would respond to council members in due course, and the invitation to view key documents is only to council members, which includes all vice-presidents.”

There had been a focus in Uefa’s list of questions about Infantino’s apparent refusal to declare why Thrive Capital – a financial vehicle founded by Joshua Kushner, the brother of Trump’s son-in-law Jared – was “selected as lead investor, without any competitive tendering process and under conditions of strict confidentiality, despite its links to the family of the recipient of the Fifa Peace Prize”.

The question adds: “Which other potential lead investors, if any, were considered before Thrive was selected, what selection criteria were applied, and who took the decision to select Thrive? How was the potential conflict of interest arising from these circumstances assessed and addressed?”
