Sir Bill Cash has said the indicative votes set to take place today are a "disgraceful attempt" to overturn the outcome of the EU referendum.
MPs will be voting on alternatives to Theresa May's withdrawal agreement today in a series of votes that are not legally binding.
"The reality is that this is in defiance of the vote of the British people," Sir Bill told talkRADIO's Julia Hartley-Brewer.
"They voted to leave, we passed the withdrawal act, and the idea that by tossing around this bag of liquorice allsorts and coming up with a whole range of so-called indicative votes which are not legal, they don't bind anybody and the fact you go through a process the effect of which you narrow it down, I don't know what the outcome of that will be."
The Conservative MP added that the move to have the series of votes on other Brexit options was a "democratic disaster".
"Over a year ago I said these people [remain-voting MPs] are trying to undermine the vote of the British people," he said.
"I had hollerings from them saying it was disgraceful that anyone should suggest such a thing. Just look where we are now. I was right then and I'm right now on this."
