any act done by a person in England and Wales would amount to the offence of incitement to commit a listed sexual offence but for the fact that what he had in view would not be an offence triable in England and Wales,

the whole or part of what he had in view was intended to take place in a country or territory outside the United Kingdom, and

what he had in view would involve the commission of an offence under the law in force in that country or territory.

what he had in view is to be treated as that listed sexual offence for the purposes of any charge of incitement brought in respect of that act, and

any such charge is accordingly triable in England and Wales.
