James O'Brien scolded "comical" Jeremy Corbyn for providing "no opposition" to the Tory party during a rant on LBC on Wednesday.
The radio show host explained why it was that the Labour leader was to blame for a fall in support for the party.
He said: "It's unbelievable. The nuttiness that's coming out of the Corbynista camp now. Everyone who doesn't agree with us must be in the pay of some mysterious organisation that's dedicated to undermining Jeremy Corbyn."

He added: "You do not need to pay anyone to undermine Jeremy Corbyn - every time he opens his mouth, you count to three and he's put his foot in it.
"This is comical. Absolutely comical. It almost makes Donald Trump look like a genius."
Many people did not take kindly to what O'Brien had to say:
To his critics, O'Brien said later on his show: "I get sent links to The Washington Post articles about how his comments on Trident weren't quite as mad as they seem.
"My point was that they seemed mad... He (Corbyn) was appearing on a television programme within a fixed amount of time in which he had to make a point and he made it appallingly badly.
"If you need a Washington Post editorial to explain what you really meant wasn't actually quite as bonkers as it seemed at the time, you're unelectable. That was my point."
