I know there was a lot of talk about England, but would it have to have been England? The British Empire was still very much in existance in those days and they had territory up the ying-yang ... why couldn't George V have sent them to some quiet little corner of the Empire where they wouldn't attract attention. What about Australia or the Falklands or something?
Yes - except the british empire was already losing influence. Despite that though, I think the arrival of the Romanovs in a remote area would have been more obvious than being well hidden in the UK - I always think of the old saying - "where better to hide a needle than not in a haystack, but among a lot of other needles". lol.
