Troubles await buyers of World Championship tickets © EuroFootball.com

Supporters who bought World Cup tickets through FIFA may face serious problems - their personal data has been stolen and sold.

As reported by the "Mail on Sunday" newspaper, 250 thousand people may have been affected, who provided their passport details and date of birth.

There are fears that the data of high-ranking officials, including Prince William of Wales, may have leaked.

It is claimed that the information was sold for half a million pounds sterling, and its source is a person involved in ticket distribution.
