This addresses my earlier thoughts - they can't live without money - if he'd been planning this and stashing money away- he'd have to had £s exchanged to euros - and there would be a trace of that - but nothing mentioned about that aspect.
Article states that other pupils parents are up in arms (as are Megans parents) that the school knew about this for so long - so too did the Council and the Police. If ever there's been a cockup of magnanimous proportions: it's got to be this considering how many people in authority were aware of this relationship, and in a position to have stopped this happening - but didn't.
Mother says if she'd been aware, there's no way she'd have allowed her extra 'maths' lessons. I'm sure she wouldn't have allowed her daughter to stay overnight with a 'friend' either that Thursday night without being able to check who she was staying with etc. As I said before, heads need to roll.
