FIFA has confirmed that an investigation will be launched into the alleged distribution of a dossier which criticised UEFA president Michel Platini.
UEFA lodged a complaint with football's world governing body on Sunday after German newspaper Welt am Sonntag published an anonymous document entitled 'Platini: Skeletons in the closet'.
It was claimed that the material from their headquarters was part of a wider "smear campaign" against Platini, who is running to replace Sepp Blatter as top boss of the scandal-hit organisation next year.
FIFA will now investigate the matter further after the 1,400-word document was sent anonymously to several newspapers.
Platini will contest next February's election with Chung Mong-joon, ex-Brazil star Zico and Liberian FA chairman Musa Bility.
