Average Brit here - we do not like this and the way politics here has been so tumultuous has shown the general public are sick of this behaviour too.

Legal immigration from South Asia dominates illegal immigration by an order of magnitude, but nobody wants to lose seats in Birmingham, so essentially doesn’t figure in the arguments about small numbers of afghans in miserable hotels in Essex.
Labour are recently leaning into being anti immigration because it's one of the few wealthy-donor-friendly policies they can pursue which will potentially gain them votes.
