Sepp Blatter says he will resign as president of football’s governing body Fifa amid a corruption scandal.
In announcing his exit, the 79-year-old Swiss has called an extraordinary Fifa congress “as soon as possible” to elect a new president.
Blatter was re-elected last week, despite seven top Fifa officials being arrested two days before the vote as part of a US prosecution.
But he said: “My mandate does not appear to be supported by everybody.”
Fifa was rocked last week by the arrests on charges of racketeering, wire fraud and money laundering as part of a US prosecution that also indicted 14 people.
A separate criminal investigation by Swiss authorities into how the 2018 and 2022 World Cups were allocated is also under way.
“I am very much linked to Fifa and its interests. Those interests are dear to me and this is why I am taking this decision,” added Blatter.
“What counts most to me is the institute of Fifa and football around the world.”
However, he was voted in for a fifth term as he beat Prince Ali bin al-Hussein of Jordan.
“I have thoroughly considered and thought about my presidency and the last 40 years in my life,” said Blatter.
“These years were closely related to Fifa and the wonderful sport of football. I appreciate and love Fifa more than anything else.
“I only want to do the best for Fifa and my institution. I decided to stand again as the best option for football. The elections are closed but the challenges we face haven’t come to an end.”
