Television presenter Jeremy Clarkson joins the farmers in Whitehall in a protest organised by National Farmers’ Union (NFU)to urge the government to change course over inheritance tax. As even the Conservative-supporting Spectator magazine wryly put it: “It is hard to believe that concerns about inheritance tax did not enter his head when he moved into farming.”Dyson is understood to deny this. It’s because married farmers can claim their £1m inheritance tax exemption (Agricultural Property Relief) twice. And then they can claim tax relief for their residence on the farm too. Why should a billionaire be able to plough all their wealth into farmland to avoid the inheritance tax every other wealthy estate has to pay?
