After weeks of warnings from Brussels on “cherry-picking” and “having your cake and eating it”, the former Tory leader hit out at EU leaders with a sharp jab.
Mr Duncan Smith praised Theresa May for her Brexit speech last week before turning the screw on the EU following an address in Parliament today.
He said: “When she gets into negotiations with her European counterparts about trade arrangements, could she remind them that cake exists to be eaten and cherries exist to be picked.”
This was met by laughter and cries of “hear, hear” from the Tory benches.
He added: “May I congratulate my right honourable friend on what I thought was an excellent speech.
“Clear and determined and giving the European Union a very clear sense of direction.
“Can I also say that in the speech I thought the most important point was to take back control.
“Would she not agree with me therefore, bringing these decisions back to a British parliament in future to make all the decisions about out arrangements is exactly about delivering that.”
Mrs May responded by saying she was “grateful” for the question and said “he is absolutely right”.
The PM continued: “When people voted they voted to take back control of our borders, our money and our laws.
“When we have left the EU decisions over our laws will be for this parliament to take. We will take back control.”
