Sigh, I still have a lot of Budget docs to read and cannot spend my whole evening doing this but go on I'll do one more...
£1m relief is on top of £1m couple allowance, so really £2m+ farms only. Only around 200 estates per year affected (av estate value £6m), just isn't armageddon for small family farms.
Imposing inheritance tax of 20% on farms worth over a million. Which is the case for many farms these days, this is money those families never want to realise.
