Funding is a question of choices. Often people can decide eg new sofa and then decide how to pay for it ie after deciding to get it eg HP, kalama, credit card, etc.Did they?
Or was it that they cancelled unfunded plans made by the previous government...
At the time it was cancelled one must assume Labour already had plans to raise a lot of money through the few means they hadn't excluded so it comes down to choosing what's important and what isn't. Just because there was no money allocated at that time does not mean there would be no money after the budget and scrapping a project tells the recipient "you are not getting it" whereas even worst case they could have said to the organisation, delay whilst we investigate funding.
