Wondering how the Fifa presidential election works? Wonder no more...

Who gets a vote?

Each of Fifa's 209 member national associations gets one vote - so American Samoa has just as much of a say as Russia.

How does the voting work?

The member associations cast their votes by secret ballot, in alphabetical order. In the first round, a candidate needs to get two-thirds of the vote to be declared the winner - if the vote is closer than that, a second round of voting is held, where a simple majority is enough.

Fifa are keen to stipulate that if they receive more ballot papers than there are members, the election will be declared void and re-run. Nothing gets past them...

Do candidates get a chance to address the Congress?

Yes, both candidates will get 15 minutes before the vote to set out their programme to the Congress.
