Under the proposals, Brussels will threaten to withdraw aid, trade deals and visa arrangements if countries refuse to take back their economic migrants. The asylum claims of more than 400,00 seekers who entered the EU in the first half of the year are likely to be rejected, posing a problem for EU leaders. Ministers from member states, including Theresa May, will discuss a text warning countries they must send more migrants home.

Increased return rates should act as a deterrent to irregular migration Document

It reads: "Increased return rates should act as a deterrent to irregular migration." Migrants fleeing war-torn countries like Syria, Afghanistan and Libya could be among those deported if their asylum bids fail. Home Secretary Ms May is expected to back the plan if it raises the changes of Calais migrant camps being cleared - despite Britain not being a Schengen country. She called yesterday for new deportation system to be able to return failed asylum seekers who do not have their own passports with them.

The plan marks a tipping point for EU leaders who have been divided over how to handle the biggest exodus of migrants since the Second World War. Under the proposals, a specialist unit of the EU border agency - called Frontex - will be created to assist with deportation. Member states that do not abide by the rules and deport "irregular migrants" will face legal action and fines from the European Commission.

The document says: "Member states must systematically issue return decisions, take all necessary steps to enforce them and provide adequate resources, necessary for identifying and returning illegally staying third-country nationals. "While member states are primarily responsible for carrying out returns, the immediate creation of a dedicated return office within Frontex should enable it to scale-up its support to facilitate, organise and fund return operations."

It came to light after immigration dominated the agenda at the Conservative Party conference, with the demanding Home Secretary unveiling a reform on the UK's asylum rules. She pledged to reduce the numbers claiming in Britain while taking in the "most vulnerable" refugees from conflict zones around the world, claiming that high migration made a "cohesive society" impossible.
