Gianni Infantino has succeeded fellow Swiss Sepp Blatter as president of world football’s governing body Fifa.
The Uefa secretary general polled 115 votes, 27 more than closest rival Sheikh Salman bin Ebrahim al-Khalifa.
Prince Ali bin al-Hussein (4 votes) and Jerome Champagne (0) were third and fourth respectively.
Blatter, who had led Fifa since 1998, stood down last year and was later banned from football for six years for breaching ethics guidelines.
The election was initially due to be fought between five candidates, but South African businessman Tokyo Sexwale withdrew before voting began in Zurich.
The first round of voting at the Fifa congress failed to determine an outright winner, though Infantino led with 88, three more than pre-vote favourite Sheikh Salman.
A simple majority of more than 50% – 104 votes – was sufficient for victory in round two.
Infantino is a 45-year-old lawyer from Brig in the Valais region of Switzerland, less than six miles from Blatter’s hometown of Visp.
An emotional Infantino told delegates that he was finding it hard to “express my feelings in this moment”.
But he told delegates that together they would “restore the image of Fifa and the respect of Fifa”.
He added: “I want to work with all of you together in order to restore and rebuild a new era of Fifa where we can put again football at the centre of the stage.
“Fifa has gone through sad times, moments of crisis, but those times are over. We need to implement the reform and implement good governance and transparency. We also need to have respect.
“We’re going to win back this respect through hard work, commitment and we’re going to make sure we can finally focus on this wonderful game.”
