Hungarian Prime Minister Viktor Orban is set to speak before the parliament of the southern German state of Bavaria Monday, despite strong resistance to the visit from opposition parties.
The event, organized by the Hungarian consul general to commemorate the 60-year anniversary of the 1956 Hungarian Uprising, will also see Bavarian premier Horst Seehofer giving a speech.
Opposition parties - including the centre-left Social Democrats (SPD) and the far-left Die Linke - have slammed Seehofer's governing Christian Social Union (CSU) for giving the increasingly authoritarian Hungarian leader a platform in the legislature.
Seehofer, one of the most vocal critics of Chancellor Angela Merkel's decision to keep Germany's borders open to refugees, last year began to align himself with some of Orban's more restrictive migration policies. The two have met on three occasions during the past year.
