Farms worth more than about $1.3 million will face an estate tax from 2026, ending a previous exemption and prompting anger in some rural communities.

They piled into central London in their thousands, mostly on foot but some in tractors, with placards reading “No Farmers, No Food, No Future” and “The Final Straw” to protest the new Labour government’s decision to impose inheritance tax on farms for the first time in over three decades.

Thousands of farmers protested at Britain's parliament on Tuesday, some driving tractors through central London, to demand the scrapping of an inheritance tax that they say will destroy family farms and threaten food production.

One Lincolnshire farmer described the planned inheritance tax as a "complete bombshell".
