What happens to the pregnant wives of the 'permanent' Armed Forces personnel in FI? They get to choose whether to remain and accept the medical care offered in FI or return to UK. Why was she not offered the same choice? The level of care in FI is actually superior to that in some remote UK locations (anyone been to RAF Valley?). Surely the choice is hers and she signs as having made that choice and taken whatever risk is deemed to be associated with it. Even back in the UK no one is ordered to live within a certain travel distance of a certain level of medical care if they are serving and pregnant.
Incidentally, she's not the first and that may have complicated the matter. I know of at least one other who was on a 4 monther there and was allowed to remain and complete her tour. No mention of her ability to mobilise at a moment's notice and defend the penguins with her SA80, she was allowed to stay. Whatever else, the RAF needs to be consistent.
