Jeremy Clarkson has unveiled a 24-year-old nurse as his new farmhand for the fourth series of Clarkson’s Farm.

The trailer for the new season left fans shocked as it showed Kaleb Cooper had left the show. Instead, Harriet Cowan, a full-time nurse and farmer, is the latest recruit to join the crew.

Clarkson, the former Top Gear presenter, said he had been left “in the lurch” by his former assistant’s departure following Cooper’s new-found fame.

Since the first episode aired in 2021, Cooper has amassed 2.7 million followers on Instagram, published a best-selling book and launched a live stage tour – The World According to Kaleb.

Clarkson bought the Diddly Squat Farm in 2008, but it was run by a villager until his retirement in 2019, after which the veteran broadcaster decided to see if he could run it himself.

Cooper, who worked for the farm’s previous manager before Clarkson took over, joined the presenter along for the ride.

Clarkson said of Cooper’s departure: “I want to make it plain that I am absolutely thrilled to bits for Kaleb.

“But, he has left me just a little bit in the lurch.”
