"From now on there can be no slogan or image whatsoever on undergarments even good-natured ones. This will apply from 1 June and be in force for the World Cup," the Fifa secretary general Jérôme Valcke told a news conference after an Ifab meeting.

Sexual statements? Just fine. Campaigns run by bookmakers - no problem. These do have a place in the game - apparently.

It's a sport, not a political platform.
