GENEVA (AP) — A spying operation on behalf of World Cup host Qatar bugged a 2017 hotel meeting between FIFA president Gianni Infantino and Switzerland’s then-attorney general during an investigation of football officials, Swiss daily Neue Zürcher Zeitung said Sunday.

The report said intelligence operatives linked to a former CIA officer wiretapped a meeting involving Infantino and Swiss federal prosecutor Michael Lauber at a Qatari-owned hotel in Bern, which also then housed the emirate’s embassy.

The NZZ report said documents and sources showed the surveillance was carried out for “Project Matterhorn” — named for the iconic Swiss mountain — to gather material on Lauber.

At the time the prosecutor was overseeing a years-long probe of football officials that had begun in 2014 with a criminal complaint by FIFA to look for suspected financial wrongdoing linked to World Cup bidders, including Qatar’s winning campaign to host the 2022 tournament.

Sunday’s NZZ article added to reporting by The Associated Press since 2021 that Qatar spent millions of dollars over several years hiring the Global Risk Advisors agency to spy on FIFA and international football officials to protect its World Cup.

After Qatar won the FIFA hosting vote in 2010, its World Cup project variously seemed at risk because of the extreme desert heat, allegations of corruption in the bid, reports of human rights and migrant labor abuses, and the economic and logistical boycott by neighboring states.

Last year, the AP reported the FBI was investigating whether agency boss Kevin Chalker’s work for Qatar broke laws related to foreign lobbying and surveillance.

The Qatari government’s international media office dismissed the NZZ report in a statement as “another attempt to spread false information about Qatar and damage its reputation. We reject the allegations and are exploring all legal avenues.”

The hotel meeting between Infantino and Lauber was revealed four years ago and is part of an investigation into their three undocumented meetings in 2016 and 2017 being conducted by two special prosecutors appointed by Switzerland’s parliament. They questioned Infantino in January.

The first two meetings were revealed in November 2018 in the Football Leaks series published by German magazine Der Spiegel.

After those reports were published, Lauber and Infantino both claimed they did not remember the content of their two meetings in 2016. They also did not acknowledge they had a third meeting in 2017 that was revealed several months later and led to Lauber losing his job.

No details have yet been revealed about the content of the June 2017 hotel meeting, either in media reports or a disciplinary investigation of Lauber by a federal office overseeing the attorney general’s department.

A March 2020 disciplinary report could not establish what Lauber and Infantino discussed though it concluded “it is obvious from the group of participants” that the wider FIFA investigation would have been part of it.

In an email reply, Lorenz Erni, a lawyer representing Lauber, declined to comment on the NZZ report which suggested the secret third meeting had for several months exposed the men to a risk of blackmail.

“The FIFA president has no knowledge of any secret surveillance actions, from whatever side,” football’s world body said in a statement Sunday about Infantino potentially being spied on. “More importantly, there has never been any even remote attempt by anyone to influence him, let alone blackmail him.”
