The Swiss Attorney General has opened criminal proceedings against FIFA president Sepp Blatter, who was questioned on Friday on suspicion of criminal mismanagement as well as on suspicion of misappropriation of FIFA money.

Swiss authorities said that UEFA president Michel Platini was also being questioned as a witness over "a disloyal payment'' of 2 million Swiss francs from Blatter in 2011 -- for work done between 1999 and 2002.
