I'm sorry but it basically is an amenesty.
The home office will be under pressure by Labour to clear this backlog that Labour have said they will sort.
So some claims will be rushed through and granted.
The ones that get refused will remain in the system because Labour won't remove any of them much like the Tories didn't.
Labour will not manage to do anything different that the Tories didn't think of doing which ultimately means removing those with no right to be here.
