“They’re a difficult watch,” Clarkson previously warned ahead of the eps dropping.

Jeremy Clarkson has revealed he has been diagnosed with an “aggressive” form of prostate cancer in an emotional episode of Clarkson’s Farm.

The former Top Gear presenter had previously warned fans that while he usually tries to keep the show “charming and cheerful”, the final two episodes of season five “are none of those things”.

“They’re a difficult watch,” he shared on Instagram.

During the episode, Clarkson told co-stars Charlie Ireland and Kaleb Cooper that he had cancer.

When Cooper asked where the cancer was, Clarkson responded: “Where it is of no concern of anybody. I’ve known since May.”

He went on to explain that he underwent a biopsy and described the cancer as “aggressive”, but had been caught at a “really early” stage.

Clarkson also revealed that he was about to undergo surgery and would be “slightly out of action” during his recovery.

Later in the episode, he confirmed the cancer was in his prostate and explained that he had undergone a procedure to remove part of it.

“The prostate, 10 per cent of it’s dead,” he said. “The 10 per cent where the cancer is.”

Speaking from a hospital bed later in the programme, Clarkson revealed that some of the treatment had “gone awry”.

“I'm going to be here for a little while,” Clarkson continued. “I don't know what's going to happen.”

“What I wanted to say was if this is all successful, I’ll see you in season six, and if it isn’t, I won’t,” he said. “Take care, everyone.”

Following the episode's release, social media was flooded with messages of support, with fans wishing Clarkson a successful recovery and speedy return to health.
