1) Get on a plane to UK
2) cut your passport into very small parts and get rid of just after landing
3) ???? (don't tell where are you from)
4) Profit after 3-4 months waiting for asylum.
At least that was standard tactics from people from arabic countries. Never say where are you from!
IMHO, it is easier to follow the rules. If you have a genuine need for asylum, then the UK is obliged, under international law, to offer it.
What the UK is not obliged to do is put up with people who try to pull a fast one; and there are a lot of those around, moresthepity.
If you present yourself honestly to the UKBA officials, with a genuine need for asylum, with relevant documentation, telling the truth, and not trying to be dodgy in any way, they will (in all probability) grant you the right to remain in the UK for a limited time.
Work with them, not against them, and they will work with you. If you have a genuine case, they are there to help you.
Unfortunately, the vast majority of people that they see are (very bad) liars, so a lot of asylum-seekers get rejected, on the basis that nothing that they say can be trusted. Of course, they have the right to appeal that judgement, but if you lie, you will get caught out, and the appeal will be rejected.
