Chris Huhne, a Liberal Democrat member of the British cabinet, says Rupert Murdoch "has to pass the 'fit and proper' test as a person to own a broadcasting organisation like Sky … and if he doesn't pass that, it's not a question of just stopping the BSkyB deal, it will be a question of him getting rid of Sky altogether".

Of course overnight it was announced that News has withdrawn the bid for BSkyB, but what does being a "fit and proper" person mean?
