UK asks FIFA to investigate Falklands banner displayed by Argentina after win

After beating England 2-1 in their July 15 World Cup semifinal in Atlanta, Argentina's players grabbed a "Las Malvinas son Argentinas" banner from fans and displayed it on the pitch. FIFA's rules prohibit political banners in stadiums. The UK government has formally urged FIFA to investigate, raising the prospect of sanctions before Argentina's July 19 final against Spain.
