Farmers have threatened to block roads across the UK unless Chancellor Rachel Reeves cuts fuel prices.
Campaign group Farmers For Action warned ministers they are considering protests unless the Government reduces tax on red diesel used for tractors, which has risen sharply since conflict began in Iran.
William Taylor, the group’s co-ordinator, told The Telegraph it had been asked to consider “UK-wide tax and fuel protests”.
He added: “There is huge concern that current policies are failing to address the pressures facing key sectors of the UK economy.”
Mr Taylor also criticised planned increases in red diesel duty, saying: “There is no common sense to this tax rise, absolutely none.”
The warning comes after similar protests in Ireland caused major disruption, with roads blocked and fuel depots targeted.
The UK Government said: “We are determined to help keep costs down. Red diesel continues to benefit from an 80% tax discount, saving farmers almost £300m a year.”
