The Slovenian was standing unopposed and will serve a four-year term.

He was confirmed in the top job at European football's governing body via acclamation. 

Delegates broke into a round of applause to confirm the move in the Italian capital.

The 51-year-old lawyer was first elected at an Extraordinary UEFA Congress in Athens in 2016 and finished the term started by Frenchman Michel Platini.

He took on the remainder of Platini's four-year term after the Frenchman, who denies wrongdoing, was banned from football for a "disloyal" payment made to disgraced former FIFA President Sepp Blatter.

Čeferin will now begin his own full term.

Other decisions taken today included the confirmation of controversial candidate Nasser Al-Khelaifi as an Executive Committee member, representing the European Club Association (ECA).

"Thank you once again for placing your trust in me," Čeferin said.

"I am both touched and honoured.

"In a world of constant and increasingly rapid change, where time seems to go ever faster and every day brings a fresh challenge, we are going to have to do more than simply adapt. 

"We are going to have to think ahead and undertake some major developments.

"We must not allow our recent short-term successes to hide the much more complex challenges that lie ahead."

Čeferin, who today announced UEFA's new OTT media platform, has endured a frosty relationship with FIFA President Gianni Infantino.

He led the opposition to the world football head's controversial reforms to the global calendar, which includes a revamped Club World Cup and new worldwide Nations League.

The Slovenian hinted that he was looking to ensure an easing of tensions.

"We will be a source of constructive ideas for FIFA, rather than one of opposition," he said.

"We are ready to work with the world governing body to ensure that football remains the world's number one sport, and that Europe continues to lead the way."

Al-Khelaifi, the chairman of Paris Saint-Germain, was confirmed for an Executive Committee role having been put forward by the ECA.

His appointment was met with opposition as his club's finances are currently being investigated by UEFA.

The Qatari himself has also previously been probed for alleged financial misconduct, but has always denied wrongdoing.

Elsewhere, seven other candidates were elected to the Executive Committee from a field of 10 candidates.

Sándor Csányi of Hungary, who was also confirmed as a FIFA vice president for Europe on a four-year term, returns to the Board.

Former Croatia international Davor Šuker and Portugal's Fernando Gomes were also re-elected but Bulgaria's Borislav Mihaylov failed in a bid to return.

Armand Duka of Albania, Jesper Møller Christensen of Denmark, Andrii Pavelko of Ukraine and Spain's Luis Rubiales have also landed seats.

Hardouin Florence of France was re-elected as the only contender for the women's position.

Gomes and Georgios Koumas of Cyprus were confirmed as UEFA representatives on the FIFA Council, and will serve two-year terms.

Reinhard Grindel of Germany was also confirmed as an ordinary member of the FIFA Council on a four-year term.

England's Greg Clarke defeated David Martin of Ireland to become a FIFA vice-president from the British associations.
