Makes no odds.
The idea of sending more than half a dozen migrants there is a complete non-starter. The island has around 800 residents and none of them have the "right of abode" there. There is next to no infrastructure, no significant hotels or other transient accommodation. Medical facilities are extremely limited: there is a small hospital which can only deal with minor ailments. There are two doctors, a dentist and a midwife.
Any accommodation required to house migrants would have to be constructed from scratch and with the only realistic communication being an RAF flight from Brize Norton, the logistical problems of such a project would be enormous, as would the cost.
It seems like an idea that a drunken Minister and his Permanent Secretary had jokingly discussed at the end of a boozy dinner.
