I totally support this. It is the only way that politicians and the wider public are going to actually be forced into action to improve things.
To fund it, I would:
Stop all vanity projects. Despite voting yes in 2014, that includes Scottish independence.
Raise income tax/Scotland use tax generating powers. We need the country to be healthy to work and drive growth.
Windfall taxes on gas/oil companies. Raise corporation tax in line with the rest of Europe.
Close tax loopholes for eg Amazon/Starbucks etc.
Reprioritise. Proper essentials eg NHS, police, local government etc would be funded, anything else, nope. Jollies to different countries for MPs stop (how much did Liz Truss spend on trips as foreign secretary?). Supporting former PMs, stop.
