Manfred Weber is an MEP for Germany's Christian Social Union and leader of the largest political group in the European Parliament, the EPP. German voters have made it clear they are unhappy with their Chancellor Angela Merkel. In two regional elections this month her conservative party, the Christian Democratic Union, suffered a humiliating defeat. The EPP isn't happy with her either, warning of a split unless she changes policy on immigration. Is this the end for Angela Merkel? And what effect has her refugee policy had on the way Germany will be governed?
