There is a question on the legality of a Labour policy on charging VAT on school fees here;
I put a wait and see answer on it a couple of days ago as the manifesto had not yet been published.
As expected the 2019 Manifesto doesn't include any intention to charge VAT on school fees and I wondered how I should proceed at this point, and if there was some more general advice on moving target questions like this.
My first instinct would be to create a second answer with "As the manifesto is now out..." the weird thing is that it would mostly say "the suppositions in my previous answer are correct". Just with some quotes from the new manifesto.
