Tabs, I think you need a fuller understanding of international asylum law than I have, to be able to comment on this stuff but key issues seem to be:
- You don't have to claim asylum in the first 'safe' country you come to (this is a common misconception).
- You should claim asylum in the country you wish to have asylum in.
- Many people have connections to the UK, other family members, language skills, whatever, which make the UK their preferred choice. Therefore, they are expected/required to claim asylum in the UK. Not least because if they claim it elsewhere, the current regime will just knock back any subsequent requests for asylum in the UK on the basis that they should stick with their first choice.
