Mrs Merkel made a "grand tour" of Europe last week in a bid to smooth over a developing row in the bloc over her open door migrant policy. She met with counterparts in Austria, Croatia, Bulgaria and Slovenia to try to get a handle of what is going on across the Shengen zone. Now as more and more states are threatening large scale deportations, the Prime Minister of Slovenia is claiming the EU is on a knife edge. Miro Cerar says that after meetings Mrs Merkel is beginning to understand the complexities facing each country. But that her 'open door policy' is no solution and that instead she should focus on protecting borders.

Prime Minister Cerar said: "The EU will not be able to improve and it’s existence is in question if it cannot solve the migrant crisis. “Angela Merkel has understood that the ‘open door politics’ is no solution for the problem. “I believe, the Chancellor of Germany has started to admit that the problem should be treated more effectively, otherwise the EU won’t be able to improve, because it cannot concentrate and will be unable to give answers to the other challenges. “If another wave of migrants would hit Europe, that would risk the security, would make the integration impossible, and would seriously put the existence of the EU in danger.”

In March, Slovenia began clamping down on migrants by introducing new border restrictions for migrants entering from Greece to Western Europe. They said they would only allow those seeking asylum in the country, or those with clear humanitarian needs to enter. Now they are calling for the EU to send more money to the Middle East, Asia and North Africa to stop the flow of migrants. Mr Cerar added: "In order to keep the people leaving their homes, Europe should provide financial and other support to those countries hit by crisis." He also warned that the EU should monitor migration effectively, so migrants arriving from the war-struck zones may enter Europe in an official, orderly way.
