There are no international laws stating that asylum seekers must seek asylum in the 'nearest safe country'.
In fact, most asylum seekers *do* attempt to settle in the nearest safe country, the UK get very few in the grand scheme of things.
The majority of asylum seekers (I wanna say 70%-80%, but I'd have to check the real figures) are granted asylum in the UK once their application is fully processed. So, the majority are genuine.
The issue we're seeing is a closure of safe and legal routes for migrants to get into this country, resulting in the need for these boats. We have also seen a reduction in funding in legal services (alongside other public services, including health care and education), which has in turn caused a backlog of asylum applications and pressures on our public services.
Where do these poor folk go while they have to sit and wait while their application is processed? They get put up in hotels for example.
Political choices and decisions have led us down the path to the point we are in now: the NHS is struggling to cope, shortage of housing etc, but rather than the ire being directed at the folk who have taken us to this point (whilst they line their pockets), we have the likes of Farage and other knobheads telling us it's the foreigners fault, and people fall for it.
This is part of the legacy of the last 14 years of the Conservatives.
