De Gregorio was a guest for Roger Schawinski’s show on German channel SRF on Monday.
The host Schawinski while closing the show asked De Gregorio to tell his favourite joke about FIFA.
After a pause for the host to comment, De Gregorio gave the answer: “The police.”
“Walter De Gregorio has decided to relinquish his office with immediate effect as Director of Communications & Public Affairs. Mr. De Gregorio joined FIFA (in) September 2011 and will serve FIFA on a consultancy basis until the end of this year,” said the official statement from FIFA.
