surely the problem with this plan is that it is designed to "stop reform" rather than actually be a real solution?

What happens to someone born in the UK to temporary refugees?

This is the cycle that fuels populist. It perpetuate policy failure while encouraging a narrative of scapegoating. The prime minister came to power promising to address it. Instead he now supports it.

My greatest disappointment with Starmer is the continuation of this same old game. Half-arsed policy with focus on electoral dynamics over effectiveness. Underlying situation gets worse. Then you complain the border is out of control, when in fact it is your policymaking which has failed.
