Labour are addicted to "redistribution" and tax rises.
My predictions, in addition to what has been announced:
Extend NI to anything subject only to Income tax at present like rental incomes (that'll lose a few more properties from the market), bank interest and share dividends - but in line with weasel words - at the current rates.
Council Tax revaluations - Blair was rumoured to want to do it and balked at the loss of votes. Maybe with a 200 seat majority Sir Keir will feel safer doing it?
Hit the motorists - lefties hate private transport. Increase fuel duty and pay per mile would be my two bets.
