Currently the UK border is in France e.g Calais, Eurostar Paris and the French border is in UK, e.g. Dover, Eurostar Waterloo.
So you are likely to have to produce your passport when leaving France.
If the French give us 6 months notice this arrangement is suspended then all you will need is a ticket and if you don't have a passport when you set foot on UK soil you just have to say "I want to claim asylum" The fold on the continent in camps have not yet claimed asylum because they are not in the country of their choice. This is often because they don't speak the language there or they have friends/relatives and somewhere to stay in Germany, UK etc
Its similar between Wales and Ireland but less formal. You just give your ticket at this end and wave your passport at the other. If you are in a vehicle they are not checked at all.
German voters slide inexorably to common sense …
