The senior Conservative figure claimed the Liberal Democrat Remainer was ignoring the plight of British citizens while seeking to amend the Brexit Bill to protect the rights of EU migrants first.
Theresa May has so far refused to offer assurances over the future of the roughly 3million Europeans who have made their home in the UK.
She has been reluctant to offer a deal because European leaders have so far refused to offer a reciprocal deal for Britons living on the Continent.
The Prime Minister suffered her first Brexit defeat after the House of Lords voted to include an amendment to the Government’s Brexit Bill, in an attempt to secure the rights of EU citizens in the UK.
Iain Duncan Smith clashed with Tim Farron over his defence of EU migrants living in the UK
This can be settled immediately if the European Union, really, behaved rather better
Iain Duncan Smith
Speaking on BBC Daily Politics, Mr Duncan Smith said: “Theresa has made this pretty clear, I think, from the word go.
“It is not in the UK Government’s intention, in any shape or form, to start kicking people out – that’s not going to happen.
“What she has said – which I think is quite logical – and I have had plenty of British citizens living abroad saying, ‘Please don’t abandon us’, because the reality is as we leave we have to protect their rights.
“I just don’t think that this close to Article 50 being triggered we gain anything from a tokenistic gesture that says we somehow place EU citizens above the UK citizens when it comes to negotiations.
“This can be settled immediately if the European Union, really, behaved rather better. They would have been able to settle this by now – it’s a stroke of a pen, ‘Yes, here’s the date, everybody can stay where they are.’”

Mr Farron, who has been calling for a second referendum to be held on the terms of any deal negotiated by the Prime Minister, retaliated by suggesting is was “symbolic” that European Union citizens hadn’t been offered a deal.
“My Point Iain, you say it’s ‘tokenistic’, you could say the same in reverse. What you do symbolises who you are and what kind of country you are,” he replied.
“It’s dangerous sending out a message to the countries to which British people currently make their home as UK citizens, that somehow the reverse of those people, who are from the EU, can be treated in this appalling way…”
Mr Duncan Smith instantly cut off his Lib Dem counterpart, raising the concerns Mr Farron was ignoring British citizens.
He blasted: “What about our British citizens? ‘We don’t really care much about you, you have a second rate value compared to EU citizens living in the UK.’”

Mr Farron’s hopes of a second vote being held on the final Brexit deal have been dashed, after the Government defeated pro-Remain peers in the House of Lords.
Europhile peers had attempted to add an amendment to the Government’s Brexit Bill this afternoon calling for a public vote on the terms of the Prime Ministers final Brexit agreement.
But peers overwhelmingly rejected the demand with 336 voting against the amendment and only 131 supporting it.
The Government has signalled it will fight to wipe out any House of Lords amendments when the Article 50 Bill returns to the House of Commons later this month.
