Do you believe mass immigration has any negative side effects, at all?

Let's say hypothetically the UK increased its population by around 3 million since 2020, including one particular influx designed and implemented by Boris Johnson to suppress wage inflation, which had a direct effect on the lower end of the job market for the native population. You could also easily argue it led to a direct surge in popularity of the far right party Reform.

Purely hypothetical of course...

You'd consider that a good thing?
