Iain Duncan Smith attacked what Stella Creasy and her Labour MPs were proposing as "endless" months of debates and amendments.
During a heated confrontation on Sky News' Ridge on Sunday, the Tory MP said all Labour amendments were irrelevant and distracting from the real issue at heart.
This came after Ms Creasy repeatedly asked the Brexit campaigner whether he would vote for Labour-proposed amendments to the Brexit Bill.
He went on to condemn MPs for delaying and diverting the Bill and said the public were "fed up" with them.

Ms Creasy said that five days was not enough to debate the Article 50 Bill in Parliament.
She told Sophy Ridge: "I think this is bigger than any political party. The Government has had to haven been pulled kicking and screaming into Parliament.
"Theresa May is not answering questions – whether it’s on EU nationals, or even the £350m for the NHS.
"You can either do it quickly or you can do it well."
But in an incredible turn, Mr Smith intervened during the heated clash and schooled his Labour colleague over what MPs were actually debating.

This bill is solely about one limited purpose and one purpose only

He said: "That money is there, it wouldn’t even be there had we voted to remain in the EU, which Labour wanted!
"These opposition amendments are not relevant. This bill is solely about one limited purpose and one purpose only.
"It gives the power to the government to invoke Article 50.
"After that you’ll have plenty of time to squabble.
"You have the whole of the European Communities repeal Act, which you can amend to the hell.
"You’ll have so many debates, if you know the House of Commons. The public will be fed up of these endless debates!"

Social media fanned over Iain Duncan Smith's intervention and praised his comments as the "only sense" on the morning politics show.
One user said that Ms Creasy had a "tendency to interrupt" while also "misrepresenting" what the post-Brexit future will look like.
Another said that the Tory politician was absolutely right, before adding: "Article 50 Bill solely about the power to notify. Future repeal legislation place for negotiation debates".
Presenter Ridge herself tweeted that she thought she was going "to have to break up Stella Creasy & Iain Duncan Smith at one point!"
