As I've mentioned before, I visited the Falkland Islands before they became famous (at a time when very few people could find them on a map of the world).
Instead of fannying about in the mud in Calais Mr Corbyn should get the RAF to ferry him down to the South Atlantic to meet the islanders (so long as he pays the full fare). He will find a group of people who are fiercely British, want nothing to do with Argentina (with many of them suggesting they would rather die than succumb to its rule) and who actually have no significant impact on the UK at all. He will also quickly learn that the result of their referendum was in no way fixed.
It is unfortunate that since 1982 disproportionate sums of money have had to be spent providing defence for the islands and this amounts to around £18k pa per islander. This, however, is scarcely their fault. Having said that, the cost of keeping any one of the people Mr Corbyn met in the mud yesterday would undoubtedly equal or exceed that and in return we would have to accommodate people who have no allegiance to this country, no particular ties to it and, in many cases, actually despise it and its values. So on balance I think I’d prefer my £18k to fund a few squaddies and erks (who, if they were not in the Falklands would probably be in some Middle Eastern cesspit “keeping the peace”) rather than to provide a council flat and copious benefits to keep a “Jungle” occupant in the manner to which he would very soon become agreeably accustomed.
