Jeremy Clarkson says he has defied doctors’ orders and led 'two coachloads' of Oxfordshire farmers to London to protest against agricultural inheritance tax changes.

The 64-year-old TV presenter, who fronts Prime Video’s Clarkson’s Farm which documents the trials of farming on his land in Chadlington, near Chipping Norton, previously revealed he had been told to cut back on working after a heart operation.

Before the march on Tuesday (November 19), Mr Clarkson told The Sun: “I will be there, despite having letters from doctors telling me not to go on the march and saying I must avoid stress.

“We have got two coaches of farmers from around here who are leaving from Diddly Squat. It is a hugely important issue.”

Addressing the rally, Mr Clarkson said: “I know a lot of people across the country in all walks of life took a bit of a kick on the shin with that Budget.

“You lot got a knee in the nuts and a hammer blow to the back of the head.”

He urged ministers to back down over inheritance tax.

“For the sake of everybody here, and for all the farmers stuck at home paralysed by a fog of despair over what’s been foisted on them, I beg of the Government to be big and accept this was rushed through, it wasn’t thought out and it was a mistake,” he said.

Mr Clarkson added: “If she (Rachel Reeves) would have wanted to take out the likes of James Dyson and investment bankers and so on, she would have used a sniper’s rifle, but she’s used a blunderbuss and she’s hit all this lot.”

Thousands have taken to the streets to protest over the changes in the recent Budget to impose inheritance tax on farms worth more than £1 million.

Addressing a crowd at the march in central London, Mr Clarkson said: “I’m off my tits on codeine and paracetamol up here.”

He said in his Sunday Times column that after being taken to hospital by an ambulance, he had an electrocardiogram (ECG), blood tests and X-rays among other checks.

Mr Clarkson said one of his arteries was “completely blocked and the second of three was heading that way” and doctors said he was perhaps “days away” from becoming very ill.

He was fitted with stents hours later, which improve blood flow to the heart.

Mr Clarkson later revealed in The Sun he had been told by his doctor that “a lot” of his current work would have to stop, but instead he opted to change his diet.

“If I didn’t work, I’d just sit at home all day, rotting,” he wrote.

“The worst problem though is diet. To cut my alarmingly high levels of cholesterol, I need to cut out, completely, ­everything I like eating.”

He has previously revealed he had to quit smoking after contracting pneumonia on holiday in Spain.

Earlier this month, it was confirmed Clarkson’s Farm, which has attracted huge numbers of fans to his Diddly Squat farm shop, had been renewed for a fifth series.

He has opened more businesses including Hawkstone Brewery at Bourton-on-the-Water and The Farmer’s Dog pub at Asthall, near Burford – since the show began in 2021.

Mr Clarkson also presents Who Wants To Be A Millionaire? on ITV, and his motoring show with Richard Hammond and James May, The Grand Tour, ended in September.
