A drip feed of no confidence letters in Mr Johnson has been issued in recent days as pressure has continued to grow.
The Clarkson’s Farm host has since called into question the constant media attention surrounding politicians breaching lockdown and being issued with fines.
Writing in his latest column, the car-enthusisast turned farmer shared his worries, as he lamented, “Will I crop a fine?”
Jeremy admitted he took the first lockdown in 2020 “very seriously” but didn’t follow suit with subsequent restrictions.

He began: “Throughout the Partygate investigation we’ve been told that Boris had some cake while another person was in the room and that Sir Starmer had a beer and a curry during a meeting with colleagues.
“And I’ll admit, I’ve been worried.”
The Clarkson’s Farm host said he washed his hands all of the time and wore a mask.
He celebrated his 60th birthday, with his girlfriend Lisa Hogan, and his children – albeit sitting two metres apart.
He wrote: “I’m all in favour of going after politicians when they make a mess, and those Downing Street wonks who vomited and had a karaoke session need a smacked bottom for sure.
“But Boris and Sir Starmer? Nah.”
Jeremy concluded: “Leave them alone on this, because they’ve got other, much more important, things to be getting on with.”
Last month, Mr Johnson received a fixed-penalty notice (FPN) for attending a birthday celebration held in his honour in June 2020, as did Rishi Sunak, the chancellor, who reportedly made just a fleeting appearance.
The PM will not receive any more fines for lockdown-breaching parties, it has since been confirmed.
Meanwhile, Sir Starmer had previously said he would resign if he received a fine for breaching Covid rules.
Elsewhere, Jeremy was recently joined by none other than Only Fools and Horses legend David Jason.
The actor flew to the presenter’s Diddly Squat Farm in a helicopter, earlier this week.
