They wouldn't get away with anything like that LG suggestion. It wouldn't survive parliament. You're right to worry though with this lot in charge.
DH and I have made an active decision to be as labour-proof as possible for the next four years. No big family spending or house moves etc. Same with our small business, just try and keep it ticking over quietly, no risks, until this period of labour batshittery is over. Self protectionism.
I'd rather bury my money in a field and leave my kids a map than let the gov take the lot when I die.
