GERMAN Business leaders are demanding Angela Merkel sets migration controls and steps in to save its £46bn trade relationship with the UK.
And they are asking for a commitment that British ex-pats living in their country and Germans living in Britain are protected under new migration proposals.
The powerful trade body, the Confederation of German Employers' Associations or BDA has demanded the EU adapts to "wish of the UK to adapt free movement."
The demands come only days after crisis hit Mrs Merkel met with new Prime Minister Theresa May in Berlin.
Oliver Zander, director general who oversees the BDA's Metal and Electrical Engineering Industries, told German news agency DPA: "There has to be balance between the interest of the business community, to keep the British as integrated as possible, and the wish of the UK to adapt free movement.
"The German metal and electrical engineering industries deliver more than 55billion euros (£46billion) worth of products to the UK each year... we should do everything to prevent a rupture. Otherwise we only damage each other."
This stark warning from German business chiefs reveals the true state of the EU and the economic desire to maintain good working relationship with the UK post Brexit.
And signals that more and more groups are demanding that Luxembourgish politician Jean-Claude Juncker, President of the European Commission, is going off course with his comments.
Mr Juncker told Britain the other 27 member states wanted to negotiate its exit plan “as soon as possible, however painful this process will be”.
After a shaky start to his speech as shockwaves reverberate around Brussels, the Eurocrat said: “Personally I am very sad about this decision but of course we have to respect it.
"This is an unprecedented situation, but we are united in our response.”
But his pushy stance has been derided by business leaders in his home country.
Luxembourg's Finance minister Pierre Gramegna told The Wall Street Journal: "We don’t want the largest financial centre in the world to turn its back on Luxembourg’s financial centre."
