The investigation had been launched in July 2020 with prosecutors investigating three alleged secret meetings that took place in 2016 and 2017, between Infantino and the former Swiss Attorney General Michael Lauber.

Lauber had been in charge of investigations in connection with FIFA between 2015 and 2019.

He had resigned in 2020 after he was implicated in the scandal.

Swiss Extraordinary Federal Prosecutors Hans Maurer and Ulrich Weder have now decided to dismiss the proceedings against Infantino.

Maurer and Weder had taken over the case in May 2021 after the previous Prosecutor Stefan Keller has been removed from his position after a court ruled he could not "guarantee a fair process."

That followed a successful complaint from FIFA over four press releases issued from his office which world football's governing body said demonstrated "extreme bias".

FIFA claimed in a statement: "The outcome of this investigation is obviously entirely unsurprising. 

"The only surprising element is only the long time taken to reach such an obvious conclusion."

Infantino, also a member of the International Olympic Committee, was in buoyant mood following the announcement.

"This is a full and clear victory for me, for the new FIFA and for justice," the 53-year-old, elected FIFA President to replace Sepp Blatter in February 2016, said.

"It is now clear that the accusations against me were mere attempts by poor, envious and corrupt people to attack my reputation. 

"If these people have some dignity left, they should at least have the decency and apologise for their actions and the damage caused.

 "Indeed and with no surprise, the investigation fully and clearly confirms that I have always acted in a lawful and correct way, always defending exclusively the interests of FIFA and football."

This is the second case this year that Swiss prosecutors have dropped against Infantino.

In March, they had cleared him of any wrongdoing over his use of a private jet in 2017. 

He chartered a flight from Suriname to Switzerland and Keller had called for a criminal investigation, which was later dropped.

"Now it is official: FIFA President Gianni Infantino has always acted absolutely correctly and lawfully in his relations with the Swiss public prosecutors who were investigating the 'old FIFA'," the International Federation said. 

"The new FIFA is today a clean, well run and robust organisation which operates in accordance with the highest ethical and governance standards."
