I repeat: it is an offence to enter the UK if you are a non UK national and there is no defence to that offence that relates to claiming asylum. An immigration officer or constable or customs officer acting under direction from an immigration officer may search a person etc for documents to establish their nationality/leave to enter/remain and a person established to be a non UK national to have entered the UK without leave can be detained by an immigration officer or constable- however guidance is that this is usually reserved for those re entering following a deportation order or those suspected of being linked to serious criminality etc. Guidance is that administrative measures such as removal from the UK or consideration as to whether they could be given leave to enter/remain (i.e. whether they may have a valid claim to refugee status) are preferred to detention and prosecution- but be clear this is not a statutory defence- this is guidance to law enforcement officers and prosecutors on practical application of the law.Let me just remind you what you posted;
"It is illegal to enter the UK if you are a non-UK national and do not have leave to enter. There is no defence to the offence that relates to claiming asylum. FYI it is simply a matter of practicality that the majority of people arriving illegally are not prosecuted for the offence"
Now apply that to my correction of your position.
It is ok to admit when you get something wrong or don't understand something properly - that's one way we learn.
