THE Christian Social Union (CSU) in Germany may use Angela Merkel's imminent collapse to push for a softer approach to Brexit and block attempts to punish Britain for voting to leave.A conflict between two sister parties in Germany - the CSU and Angela Merkel's Christian Democratic Union (CDU) - has placed the Government on the brink of collapse. The German rupture rests on migration, with the Interior Minister Horst Seehofer advocating laws that would turn back refugees at the border - something Mrs Merkel has ruled out. Monika Hohlmeier, a German MEP who is a member of the CSU, said that Mrs Merkel's fall was not her party's end goal but refused to say whether the party would be willing to oust the leader to achieve their policy. However, in an unlikely turn, the threat to Mrs Merkel's future and the current migration row could have a huge impact on the future of Brexit talks.Speaking to the BBC's Mark Mardell on The World This Weekend, Mrs Hohlmeier suggested that the CSU would join a growing contingent of European parties calling for a stop to the European Commission's punishing approach to Brexit. Mardell, who called the CSU defiance a "Bavarian revolt," said: "We have heard that the CSU might play a role in arguing that the German government has to reach some economic compromise with Britain. Is that true?" The German politician responded: "Bavaria has many links to Great Britain, and we would like to have a good relationship to Great Britain, especially because our Bavarian companies have a lot of economic links so we don’t wish to interrupt the different product lines. "There are lots of product lines where part of the production is in Bavaria and the other in the Great Britain."
