Fifa president Sepp Blatter resigns

Sepp Blatter has announced he will step down as president of Fifa, calling an extraordinary congress "as rapidly as possible" at which a successor will be selected.

The Swiss announced his decision at a hastily-arranged press conference on Tuesday after his secreatry-general Jerome Valcke had earlier been implicated in the US Department of Justice's investigations into a $10m payment to indicted former Fifa vice-president Jack Warner.
