But is Andrew a sex offender in this country?
I would say that someone who knowingly has sex with someone who has been trafficked is a sex offender, yes. Wherever it happened, and wherever he resides. As I understand it, private islands do not operate outside of legal jurisdictions, so owners and guests, however wealthy and/or 'well-born' are not at liberty to disregard legislation.
If the trafficked girl was also of an age with the offender's daughters it adds a very distasteful dimension, and if he lied publicly about knowing her whilst admitting privately that he did, adding that there 'might be' a photograph of himself and the trafficked girl then that points very clearly to his being fully aware that he was committing an offence.
