Farmers have dominated the debate over the recent Budget's change to inheritance tax – but the issue is much wider than that. Family businesses are affected in the same ways, and there are many more of them.
As the implications dawn on many such families, there are warnings of lower investment, lower employment, lower growth and the potential takeover of a vital part of the economy by big, and often foreign, corporates.
The change comes from the chancellor's decision to tax assets as they pass from one generation to another.
For most people, that tax kicks in for assets worth more than £325,000, or £500,000 if the family home is being passed on.
But for farmers and businesses, passing on assets from one generation to the next is currently tax free - and that tax relief has been unlimited.
Chancellor Rachel Reeves plans to exempt the first £1m of agricultural or business property. After that, it will be taxed at 20% - half the rate of inheritance tax required from others.
