Sepp Blatter says he will resign as president of world football's governing body Fifa amid a corruption scandal.
The 79-year-old Swiss was re-elected last week, despite seven top Fifa officials being arrested two days before the vote as part of a US investigation, but has called an extraordinary Fifa congress "as soon as possible" to elect a new president.
Fifa was rocked last week by the arrests on charges of racketeering, wire fraud and money laundering as part of an investigation 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.
