And how would independence happen with no devolved government in Scotland? After Reform had removed the mechanism for running an independent Scotland?
Apropos of nothing, Starmer has hinted at similar 'reforms' himself.
There is no official policy from Reform to reverse devolution. So you are probably listening to some random noise from one of the headless chickens in the party.
Neither has Labour, incidentally. I think you are conflating the stance on things like a further referendum and actually applying the current boundaries of the devolved and reserved powers as limiting them.
The SNP has consistent sought to develope independent foreign policy, for example, which is reserved. The last government quite rightly told them to stop spending their money on it and to stop undercutting UK foreign policy.
