Let me just put that in context. Firstly, we have had inheritance tax or one of its predecessors since 1694. It is, in fact, of exactly the same age as the national debt, precisely because the existence of both makes sense.
At least since 1066 in fact.
And vast chunks of Magna Carta are on the allowable limits to such governmental extortion.
Following Magna Carta of 1215, the standard rates became one quarter of a year’s profit of the estate payable by an under-tenant, and a full year’s profit payable by a non-baronial tenant-in-chief.
A year’s income from the estate inherited.
So, those who would have inheritance tax at 40% of capital value – can we get medieval on their arses down at Runnymeade?
