Mark Francois has slammed the British establishment's "superior smugness" in an appearance on the breakfast show.
The European Research Group's vice-chair named MPs Yvette Cooper and Dominic Grieve in a rant about those with influence attempting to "frustrate Brexit", grouping them in with senior civil servants and prominent media personalities.
"Why have we not left? Because the British establishment, and by that I include senior civil servants in Number 10, the Cabinet Office, a number of MPs like Yvette Cooper and Dominic Grieve and others, people prominent in the media, all of whom have never accepted the result of the referendum," he told talkRADIO's Julia Hartley-Brewer.
He continued: "They have been doing everything they possibly can to frustrate Brexit and the public now see that."
Turning his attention to the upcoming EU elections - which were given the go-ahead by the government yesterday - the Conservative MP for Rayleigh and Wickford said it was "£150 million" that "could have probably been spent better elsewhere".
"The one upside of the fact we're having these elections is that on May 23, the British establishment in all their cosseted, feather-bedded, oh-so-superior smugness are going to get the shock of their bloody lives."
