The German Chancellor Angela Merkel was handed a report on Wednesday by her top economic advisers urging her and other European politicians to block Britain from exiting - despite the country’s referendum result. In a move which Brexiteers will see as outrageous meddling in the June 23 referendum result for Britain to exit the EU, the German Council of Economic Experts also warned that, in its view, leaving the bloc was not a done deal. The annual report said the European Union will not be better off without Britain. It stated: “The German Council of Economic Experts calls for constructive negotiations to prevent an exit, or at the least to come to an agreement that minimizes the damage on both sides.”

The group behind this 2016 dossier are known in Germany as the "Wise Men." The German Council of Economic Experts is an independent academic body set up in 1963 to advise the German government on macroeconomic policy. Throughout the report the authors suggest Brexit may not even happen. It also suggests even after Britain triggers Article 50 - the nuclear trigger which will signal the country's retreat from the legislatures of Brussels and Strasbourg - "Brexit can still be prevented."

Political actors should not assume too soon that the Brexit is a done deal

The report states: “Due to the consequences, political actors should not assume too soon that the Brexit is a done deal.” German media said Mrs Merkel and other leaders may not draw red lines on concessions which London might demand - interpreted by many as a reference to Britain's wish to impose immigration controls on EU migrants. But the report added: “A stance which is too lenient could encourage others to become copycats, with unforeseeable consequences.” The economist group says though that the short-term economic impact of Brexit on Germany will be "moderate" and predicts that its strong economy will be sturdy enough to handle the aftershocks of withdrawal.

It is Britain, they say, which stands to lose the most in any split with the EU. Despite the advice given by the experts - Merkel has already said the decision is must stand. She said: "The whole process of the exit still lies ahead of us, but the decision is irrevocable. "Now we must negotiate on the basis of our interests. And 'negotiate' means, above all, strengthening common projects." While she said the EU's relationship had to remain friendly, she added: "But on the other hand, we must also hold together the 27 (other EU countries) and can not set standards, which allows everyone to cherry pick to their liking in the end."
