//Since the majority of those who reach our shores are intercepted by various maritime agencies, your useage of the 'i' word is at best... a misnomer!//
I doesn't pay to get hung up on the language used. It diverts from the issue (which perhaps is the intention of some people). If the term "invasion" offends some people they will have to get over it. Whatever you might call this influx, those involved are not invited and they are not fleeing for their safety. They are in France. If they were French citizens living in Paris, would they be treated in the same way? No, because they are in a safe country and not in any danger.Neither are those coming here in rubber boats (until they set forth in the boats, that is).
To concentrate on Albanians for a moment, around 55% of Albanian asylum applications to the UK are successful. In Germany, Sweden and a few other European countries that figure is zero. In France it is 2%, Ireland 3% and Spain 4%. So why are they treated so differently in the UK, which is subject to just the same UN treaties as the others I have mentioned? The answer lies in Mrs May's ridiculous "Modern Slavery" legislation which those coming here exploit. Many of the arrivals from Albania claim to have been "trafficked" from there by criminal gangs. Albania is a peaceful country which has not been at war for 25 years and it has an advanced law enforcement and judicial system. So the issue of abduction is a matter for the Albanian authorities to address; it is not one that can be sub-contracted out to another country. In the north of England there have been many cases involving girls and young women being exploited and abused by (mainly) Muslim men. Using the same argument as the Albanians, they should be able to set off for France and claim asylum there. This is clearly ridiculous; the issue of their safety is one for the UK authorities.
The Modern Slavery Act (or at least its interpretation) is something else the government needs to address. It is clearly allowing large numbers of people to remain here under the guise of "asylum" who realistically have no such right. For its part the UN has moved the goalposts and now believes it is quite acceptable for large numbers of people to roam the world, seeking a destination of choice because they don't like it where they are. That was not the purpose of the 1951 treaty and Article 31 clearly makes a distinction between those people and those who arrive directly from a country where they are in peril.
These are the issues the UK government needs to address. They should not be concentrating their minds on what to do with people after they have arrived, they should prevent or deter them from arriving.
