That is correct, but I would imagine if the Crown was to pursue a prosecution of an alleged crime such as this against the named victims wishes, and again I would assume he would be the key witness & probably the only person able to provide a credible account of events, then it's pretty much a waste of time of the judicial system, if he was not wanting her found guilty when he took the stand. I know absolutely nothing about this, so it could well be She had gone all Stan Collymore on him in a public place, then obviously She would be staring down at almost inevitable conviction by her peers in Crown court. It then wouldn't have mattered what degree of punitive justice was handed down to her, the press would have gone to town & game over career wise in the public domain.
An absolute tragic waste of a life if it was the pressure of it being put out by the media for public consumption, a very sad sad outcome indeed, for what was probably no more than a bit of a (very) heated ding dong in a relationship.
