Boris Johnson has taken a page from Nigel Farage's playbook and pledged to deliver an Australian-style point-based immigration system if he becomes prime minister.
The would-be Tory leader said he wanted to restore the public's faith in the UK's immigration system and to be "tougher on those who abuse our hospitality".
Mr Johnson said he wanted to "learn from" Australia, which he said had a simple system based on contribution, fairness and control.
He said: "We will restore democratic control of immigration policy after we leave the EU.
"We must be much more open to high-skilled immigration such as scientists, but we must also assure the public that, as we leave the EU, we have control over the number of unskilled immigrants coming into the country.
"We must be tougher on those who abuse our hospitality. Other countries such as Australia have great systems and we should learn from them.
The policy has long been a favourite of the British right - with Nigel Farage calling for a similar plan since 2015.
But last night business leader said the plan would be a nightmare for employers.
CEO of London First Jasmine Whitbread said: “A points-based system would be a bureaucratic nightmare and won’t deliver the skills the economy needs to grow.
“A new salary threshold for overseas workers, set in line with the London Living Wage, would enable business to access talent, avoid a recruitment cliff edge and ensure workers are decently paid.”
The former foreign secretary said the scheme would also seek to protect EU nationals' rights.
"This should have happened straight after the referendum," he said.
"I will sort it out immediately and make sure that this issue is properly dealt with and millions of people can stop worrying."
The Immigration and Social Security Co-Ordination (EU Withdrawal) Bill is currently at report stage and contains plans to end the existing automatic preference for EU citizens.
However, the Bill does not set out the details of what the new immigration system will look like from 2021, and a consultation to shape this is not due to report back to parliament until the end of this year.
Mr Johnson said he would ask the Migration Advisory Committee (MAC) to incorporate elements of the Australian points-based system into the UK's new law.
He would ask the MAC to consider a contribution, including a firm job offer before arrival, the ability to speak English and blocking the ability to claim benefits immediately.
Mr Johnson also committed to making sure that the three million EU nationals living in the UK would have their rights protected if the UK leaves without a deal, and said he would continue the rollout of "settled status" and "pre-settled status" scheme as before.
