Immigration is sucking support more from the tories than labour. They rode into power based upon a promise to do something about it and then massively increased it.

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.

Decided not to, but continued to actively campaign on. It’s created a really weird situation where the actual policy choices are hugely disconnected from the rhetoric and emotion in the debate.

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.

For the Conservatives it's all about irregular/illegal immigration. Labour are hugely unpopular on that having apparently no idea what to do about it but they also have massive challenges on the economy/cost of living and the state of publicly funded services.
