German Chancellor Angela Merkel has congratulated Hungarian Prime Minister Viktor Orban on his election victory, a German government spokesman said on Monday. “As is customary after elections in Europe, the chancellor congratulated the election winner, Prime Minister Orban, on his success in the Hungarian parliamentary elections in a letter,” Steffen Seibert said. Merkel will work with the new government in Budapest despite differences on migration, according to the spokesman. “It is quite obvious that there are also controversial issues in our cooperation, the different stances in migration policy come to mind,” Reuters quoted Seibert as saying.
