Britain could face its first-ever national farming strike this Sunday in protest at Labour’s inheritance tax raid.

Welsh pressure group Enough is Enough called on “those who are able” to begin a week-long strike with the aim of stopping produce leaving their farms.

In a leaked statement, reported by the Times, they said: “We are being suffocated by a government that seems determined to destroy our livelihoods, our future and our ability to feed the nation.

“This country will be facing massive food shortages with potential significant price increases and the demise of the rural economy along with a serious implications of food security.

“We simply cannot allow the destruction of our industry to continue and our responsibility to feed our nation be taken away. This is a last resort but we as farmers are in despair as we simply cannot af ford to provide food to the public.

“We ask this government to talk to us, to listen to us, and allow us the freedom and flexibility to feed our nation.”

Inheritance tax relief allows farmers to pass on their land and property tax-free to their families, either within their lifetimes or in their will.

But Chancellor Rachel Reeves announced at last month’s Budget that the 100% relief for family farms would be limited to only the first £1million of combined agricultural and business property.

For anything above that, landowners will pay a 20% tax rate, rather than the standard 40% rate of inheritance tax applied to other land and property.

The move has caused uproar among farmers, unions and opposition parties.

They have warned it will have a devastating impact on the future of farm businesses, forcing many to sell land and reduce their business viability, as well as making Britain more reliant on imports.

Ministers have insisted that only about a quarter of farmers – the largest landowners – will be affected.
