Fifa President Sep Blatter's re-election bid has been thwarted at least for the moment, after first-round ballots did not return the top footballing administrator with the 66% majority he needed to secure a fifth term.
His rival, 39-year-old Jordanian Prince Ali bin al-Hussein, secured 73 votes in the first round, depriving Mr Blatter, who got 133 votes, of an easy victory.
The vote will now go to a second round, where the winner will need to secure more than 105 votes to become the next Fifa president.
The two men endured over an hour-and-a-half's wait while the 209 football associations in attendance cast their ballot one-by-one, in the privacy of a voting booth.
It was revealed that three votes were spoilt and discounted.
The 2015 Fifa Congress was dogged by controversy after high-ranking officials close to Blatter, including his Vice President Jeffrey Webb, were arrested in a dawn raid just days before by US officials as part of a suspected $150m bribery sting.
On its opening day, the event was riddled with high drama, as first protesters had to be removed by security, then police warned of a bomb scare, and finally intense last-minute negotiations over a plot to ban Israel from world football, all threatened to overshadow the day's events.
