It looks like he's admitted to kissing a girl of 15, knowing she was 15, and grooming. The more serious other 2 he's denying by the looks of it. I'd guess his top of the range expensive lawyers will get him off with the other two, and he'll be charged for those 2 minor offences? Can't see him getting too much punishment for that, they let off a lad for raping a 5yr old the other week:

That's disgraceful. Judges have too much power when it comes to sentencing.
