I think this is sarcasm, but just to spell it out: this is a causation/correlation fallacy. Immigration is a result of global trade, not its cause. Brexit killed the trade part without actually doing anything about immigration policy.

The incredibly stupid part of all this is that the conservative government insisted on wrecking the trade side because reducing immigration was deemed more important, and then entirely voluntarily issued a lot of work permits.

(without even getting into the more obligatory areas of immigration like refugees and marriages)
