To Blackpool Rock's excellent post of this morning, I would add this.
Others may be better informed than me about the practical, logistical and legal difficulties in limiting immigration or removing illegal immigrants. However my understanding of the matter is that, if Reform UK came to power, they would be likely to have no more success than any other government in either respect.
Nonetheless, a significant proportion – possibly most – of Reform UK’s adherents almost certainly support the party largely because they erroneously believe that it has a magic bullet to deal with excess immigration.
I even suspect that quite a lot of Brexit supporters thought, in some muddled way, that a vote for Brexit would mean there would be fewer “tinted” immigrants (to use the late Dame Edna Everage’s terminology) into the UK – as if Bangladesh, Nigeria and Indonesia were members of the European Union. Just as Australia participates in the Eurovision Song Contest.
This is the thing that again I think many people are under the impression that within a very short space of time 1000's of people a day will be sent packing however I believe it requires us to leave the European court of human rights which will take some time if it's actually possible / voted through or whatever.
It will actually require a massive scaling up of the entire operation which will cost a lot of money, Ok so you could argue that you then save money in the longer term however and this is a key point -
Deportations require the receiving country to accept the return of their citizens and countries often refuse to accept enforced deportations without diplomatic agreements.
I'm not exactly sure whether a person from say Nigeria who actually came from France would be returned to Nigeria or France

What i'm confident about however is that if Reform got in and left the ECHR then France would tell us to fuck off regarding accepting anyone back, additionally any current measures trying to stop people crossing would be out the window and i'm also thinking they may well round up illegals throughout France and point them in our direction
Regarding country of birth if as is claimed so many of them ditch their passports and papers etc and then refuse to say where they are from then i'm not sure how you return them to the country but if they are also murderers / various criminals (again as we're led to believe) then surely their own country will say we don't want them and you can keep them.
Ok so i've just found this which is almost a year old but does seem to be what Farage is or was proposing, it then talks about the legalities etc
