MP Mike Gapes has called for a "fundamental reform" of Britain's political system.
The Change UK member said he believed politics was "broken" and was driven by "ideology and prejudice" during an appearance on the breakfast show.
"We need to have fundamental reform because the old parties have failed us," he told talkRADIO's Julia Hartley-Brewer.
"Far too much in politics at the moment is driven by ideology and prejudice, not based on the evidence."
His comments come in the wake of the local elections, and ahead of Theresa May's meeting with the 1922 Committee chair, Sir Graham Brady, after she was asked for "clarity" on when she plans to resign.
"The thing that is clear in the local elections... both the Conservative Party took an absolute hammering, and the Labour Party, which ought to have been able to capitalise on the unpopularity and incompetence of the government," Mr Gapes added.
"The two big parties are really discredited."
