Sepp Blatter's reign at the top of FIFA is set to come to an end in the next four months after he announced his resignation from the presidency, here we look back at his 17-year tenure.
Early Years
Having joined FIFA in 1975, Blatter moved from his role as technical director to that of general secretary under the presidency of Brazilian Joao Havelange.
Presidential reign begins
After 17 years working for Havelange, Blatter succeeded his mentor in 1998 as he beat former UEFA president Lennart Johansson in the presidential election. Despite being the underdog, Blatter received 111 votes to Johansson's 80 and was handed victory when the Swede conceded defeat before the second ballot.
Criticisms and allegations emerge
Having brushed off allegations of bribery in 1998 Blatter was at the centre of another scandal three years into his first term, a FIFA investigation into the collapse of marketing partner labelling the president "clumsy" but confirmed he had no involvement in any "criminal or ethical misconduct."
Re-election for second term
Despite 11 members of the FIFA Executive Committee filing criminal complaints against him, Blatter won a second term at the top of football's governing body in 2002. Cameroonian candidate Issa Hayatou was his challenger, but he was unable to stop the popular president being re-elected, Blatter winning 139 of the 195 votes cast.
Spreading the World Cup
Part of Blatter's presidential promises was to take football to all continents around the world and give some of the non-footballing powerhouses the chance to host the global showpiece - a promise he kept throughout his tenure. Having taken the competition to South Korea and Japan in 2002, it was the turn of South Africa in 2010 - the first African nation to host the event. Blatter continued his push to make the competition a global event, and minnows Qatar were awarded hosting rights for 2022.
Third term secured
Blatter earned himself a third term in office in 2007 when he ran unopposed for re-election, his popularity across the footballing world continuing to grow despite previous allegations. However, the next big scandal began his slippery slope out of office. In 2010 the bidding process for the 2018 and 2022 World Cups saw controversy rain down on the organistation - and Blatter - as Russia and Qatar were awarded the finals. Accusations of bribery, financial mismanagement and bid-rigging were made, although again none implicated the president.
Garcia investigation
Amid the controversy surrounding Russia and Qatar's bids, a FIFA Ethics Committee investigation into the process declared violations of their code had occurred, but deemed they had not affected the integrity of the vote. The man who provided the research into the two bids for the committee - Michael Garcia - produced a report detailing his findings.
However, the full details of the report were never announced and Garcia quit from his role in protest following the Ethics Committee's verdict. The football world are still waiting to hear Garcia's findings in full.
Re-election unopposed
Although Mohamed bin Hammam put himself forward as a presidential candidate to rival Blatter in 2011, the Qatari soon withdrew his bid after reports of bribery for votes during his campaign. Blatter was duly re-elected.
Scandal rocks 2015 FIFA Congress
With a fifth election only days away, FIFA was thrown into turmoil on May 27 2015 as Swiss authorities arrested nine FIFA officials as part of a United States Department of Justice investigation in corruption allegations.
Blatter was again not implicated but the scandal marred the upcoming election against Prince Ali bin Al Hussein, however the Swiss prevailed once again as he secured enough votes to win the first ballot before Prince Ali withdrew.
Resignation
The re-elected president promised to "fix" FIFA after securing a fifth term but four days later, amid more controversy over an alleged bribe paid by the South African government for the 2010 hosting rights, Blatter resigned.
