Aldi also backed calls for a pause. It said: “We all need a farming sector that can confidently invest in its future and continue to produce high-quality British food.”

“That’s why we are supporting the farming community’s calls for the Government to pause the implementation of its proposed changes to inheritance tax until a further period of consultation has taken place.”

A Lidl spokesperson said the supermarket giant is “concerned that the recent changes to the Inheritance Tax (IHT) regime will impact farmer and grower confidence and hold back the investment needed to build a resilient, productive and sustainable British food system.”

The German supermarket called for a full consultation. It said: “We will be raising our concerns with the government at any opportunity we get.”

Marks and Spencer also released a statement on Wednesday which said that it had been working closely with the farming unions and that it supports the NFU’s call “to pause the policy while a full consultation is carried out.”

“We support calls for the government to pause the changes to IHT and to consult with the industry to ensure they avoid placing risk on the investment needed to guarantee the future of UK food security, the protection our countryside, and the safeguarding of a vital part of our national life,” the spokesperson said.

The spokesperson said M&S has raised its concerns during its own discussions with the government.

Last October, Chancellor Rachel Reeves announced that farms worth more than £1m will be liable to pay 20% inheritance tax from April 2026.

Previously, farms and agricultural businesses have been exempt from death taxes.

In December, protesters drove tractors through Westminster to protest.

At the time, NFU president Tom Bradshaw told MPs farmers were ready to work with the government, adding there were “many ways” to make the policy “less bad”.

However, Sir Keir Starmer insisted the “vast majority” of farmers would not be affected by the tax changes.
