You can only hope someone had warned them this is how parliament works. They don’t get to choose what is voted on, only how they vote.
They voted to keep it. It’s what having a majority allows you to do, decide on policy.
You and @Brewster's millions are not stupid. You both know what was in the Labour manifesto, and the thousand and one times they've said it will only contain policies they can fund through immediate savings.
How many hundreds of interviews have ministers done saying that there are things they'd "like to do" but not until they can identify how to fund them. Expecting that to change, when we've not even had the first budget, and just because of some performative politics from the SNP, is disingenuous to say the least.
